Delrin CNC 加工通常比 PTFE 更容易控制, 尼龙, 或许多软塑料.
But that does not mean every Delrin part is simple.
德尔林, also commonly discussed as POM or acetal, is widely used for custom CNC machined plastic parts because it offers a practical balance of machinability, 低摩擦, 尺寸稳定性, 磨损行为, 和成本.
It is often used for:
- 衬套
- 滚筒
- 齿轮
- 垫片
- 耐磨垫
- 袖子
- 滑块
- guide blocks
- 阀门零件
- 夹具组件
- electrical insulating parts
- low-friction mechanical parts
Delrin can machine cleanly, hold crisp edges, and produce good surface quality with the right process. 然而, it still needs proper review when the part has tight tolerances, 薄壁, 小螺纹, 压配合, long bores, snap-fit features, 滑动面, 或检验要求.
A good Delrin machining plan should review:
- exact material grade
- POM homopolymer or copolymer requirement
- 库存形式
- 壁厚
- bore and sleeve stability
- thread design
- sharp corner risk
- 毛刺控制
- moisture and temperature condition
- 表面饰面
- 检查方法
- mating parts
- application load
- quantity and repeatability
The goal is not to make Delrin machining complicated.
The goal is to avoid treating Delrin like metal when the part function depends on plastic behavior.
What Is Delrin CNC Machining?
Delrin CNC machining is the process of cutting Delrin or POM stock into custom parts using CNC milling, 数控车削, 钻孔, 无聊的, 窃听, grooving, or secondary machining operations.
Buyers may use different terms in RFQs:
- Delrin parts
- Delrin machining
- CNC Delrin
- Delrin CNC machining
- POM CNC machining
- 聚甲醛加工
- acetal machining
- acetal CNC parts
- POM bushings
- Delrin gears
- machined acetal components
In many RFQs, “Delrin” is used as a practical shorthand for acetal or POM plastic. 然而, the exact material grade still matters.
The drawing or RFQ should clarify whether the part requires:
- Delrin brand material
- POM均聚物
- 聚甲醛共聚物
- black POM
- natural white POM
- food-contact grade if required
- 玻璃填充的, PTFE-filled, or modified grade if required
- material certificate if needed
Do not rely only on the word “Delrin” when the application has strict mechanical, 化学, 食品接触, 医疗的, or dimensional requirements.

Why Delrin Is Popular for CNC Machined Parts
Delrin is popular because it machines cleanly and performs well in many mechanical applications.
Compared with softer plastics, Delrin usually offers better stiffness, cleaner chip formation, and more predictable feature control.
Compared with high-end plastics such as PEEK, Delrin is usually more cost-effective for moderate-temperature mechanical parts.
Compared with nylon, Delrin generally has lower moisture sensitivity, although humidity and application environment should still be reviewed.
Common reasons buyers choose Delrin include:
| 要求 | Why Delrin May Help |
|---|---|
| 低摩擦 | Useful for sliding parts, 衬套, 滚筒, and guides |
| 良好的机械加工性 | Produces cleaner chips and sharper features than many softer plastics |
| 尺寸稳定性 | Often more stable than nylon in many normal environments |
| Wear behavior | Useful for moving mechanical parts in selected applications |
| 电气绝缘 | Suitable for many non-conductive mechanical components |
| Cost balance | More affordable than many high-performance plastics |
| 良好的表面质量 | Can produce clean machined surfaces with proper tools |
| 刚性 | More rigid than PTFE and many soft plastics |
| 重复性 | Useful for prototype and low-volume mechanical parts |
Delrin is often a good starting point when a plastic part needs mechanical function but does not require the high temperature or chemical resistance of PEEK.
For material comparison against PEEK and POM, 看看我们的 PEEK vs POM CNC machining 指导.
When Delrin May Not Be the Best Choice
Delrin is useful, but it is not always the best plastic.
Before selecting Delrin, the buyer should review the real application conditions.
Delrin may need extra review when the part has:
- high service temperature
- continuous heavy load
- strong chemical exposure
- very tight press fits
- long-term creep risk
- ultra-low friction requirements
- high-wear abrasive contact
- thin snap-fit arms
- very small threads
- 食物, 医疗的, or regulatory requirements
- low-outgassing requirements
- cleanroom or semiconductor requirements
- high moisture or outdoor exposure
- parts that must be bonded or painted
在某些情况下, 窥视, ptfe, 尼龙, 聚乙烯亚胺, 聚苯硫醚, UHMW, or another plastic may be more suitable.
例如:
| 要求 | Possible Better Material |
|---|---|
| Higher temperature and strength | 窥视 |
| Very low friction and chemical resistance | ptfe |
| High impact and toughness | 尼龙 |
| Very low-cost prototype housing | ABS |
| Transparent part | Acrylic or polycarbonate |
| Higher chemical and thermal resistance | 聚乙烯亚胺, 聚苯硫醚, or PEEK depending on use |
Delrin should be chosen because its behavior matches the part function, not only because it is easy to machine.
Delrin vs POM vs Acetal: What Buyers Should Specify
德尔林, 聚甲醛, and acetal are closely related terms, but they should not always be treated as identical in RFQs.
POM is the material family. Acetal is another common name for POM. Delrin is a well-known trade name often used for acetal homopolymer material.
In many standard CNC projects, buyers use these terms loosely. That may be acceptable for simple prototype parts, but it can create problems when the part has functional requirements.
The RFQ should specify:
| Material Item | 为什么它很重要 |
|---|---|
| POM均聚物或共聚物 | Different grades may behave differently in strength, 稳定, 和耐化学性 |
| Brand requirement | Some drawings require actual Delrin brand material |
| 颜色 | Natural, 黑色的, or other color requirements may affect stock availability |
| Certificate need | Some projects require material traceability |
| Application condition | 温度, 加载, 穿, or chemical exposure may affect grade choice |
| Regulatory needs | Food-contact, 医疗的, or industry requirements must be stated early |
| Filled grade | PTFE-filled, 玻璃填充的, or modified grades may change machining behavior |
Buyers should also be aware of the internal structure difference between POM homopolymer and POM copolymer. Thick Delrin or POM-H rod stock may contain centerline porosity near the core of the material, depending on stock size and manufacturing method.
This may not matter for many standard bushings, 滚筒, 垫片, 齿轮, or non-pressure mechanical parts. 然而, it can become important when the part is used for fluid sealing, pressure-tight valve seats, manifold-style components, or features where internal leakage is not acceptable.
For pressure-sensitive or sealing-critical Delrin parts, the supplier may review POM copolymer, suitable stock size, stock orientation, machining position relative to the material core, or another material grade before production. If leakage risk is critical, the RFQ should clearly state the pressure, 体液, 密封要求, 及检验方法.
A better material note is:
材料: 聚甲醛 / acetal, 黑色的, supplier to confirm grade before production. Material certificate required if available.
If the exact grade is critical, the drawing should state it clearly.
Delrin Machining Risk Map
Delrin machining risk usually appears in specific features rather than across the whole part.
| 特征 | 主要风险 | 回顾什么 |
|---|---|---|
| 薄壁 | Deflection, 喋喋不休, or spring-back | 壁厚, 支持, roughing sequence, 最终检验 |
| 小螺纹 | Weak thread form or burrs | 螺纹尺寸, engagement length, 配合螺丝, 装配扭矩 |
| 压配合 | 压力, 开裂, or creep over time | Interference amount, 加载, 温度, mating part |
| Snap-fit arms | Stress concentration or breakage | Radius, 厚度, 方向, repeated flexing |
| Long bores | Taper, ovality, or measurement variation | Tool support, boring method, inspection pressure |
| 齿轮 | Tooth burrs, 跳动, or fit problems | Cutter strategy, bore datum, tooth inspection |
| 滑动面 | Tool marks or friction variation | Surface direction, 结束, mating material |
| 尖锐的内角 | 应力集中 | Corner radius, cutter diameter, DFM change |
| 小孔 | Drill wander, 毛刺, or breakout | 孔深, drill geometry, backup support |
| 化妆品面孔 | Tool marks or handling scratches | 表面光洁度, 去毛刺, 包装 |
This risk map helps prevent a common RFQ mistake: assuming that clean machining automatically means every Delrin feature can hold metal-like tolerances.
Tolerance Planning for Delrin CNC Parts
Delrin can often hold good tolerances for a plastic material, but tolerance still depends on geometry and inspection condition.
A thick, compact Delrin part is usually easier to control than a thin, long, 灵活的, or heavily pocketed part.
Tolerance planning should review:
- 零件尺寸
- 材料等级
- 库存形式
- 壁厚
- unsupported length
- 加工顺序
- 内应力
- 夹紧方式
- temperature condition
- 水分状况
- 测量方法
- final application
- mating parts
- 生产数量
Although Delrin is more dimensionally stable than many soft plastics, raw stock shapes can still contain residual internal stress from extrusion, 成型, or stock manufacturing. When a machining setup removes a large amount of material from only one side of a plate, 住房, or thick blank, the stress balance inside the part can change.
This can lead to slight bowing, flatness change, or shape movement after unclamping, especially on flat plates, 财力雄厚, thin covers, and asymmetrical parts.
For tight-tolerance Delrin parts, the supplier may review stress-relieved stock, balanced two-sided material removal, staged roughing and finishing, or a short stabilization period before final sizing. This helps reduce the chance that a part looks correct during machining but shifts before final inspection or assembly.
A drawing should not apply tight tolerance to every feature by default.
反而, separate the part into:
- functional features
- 滑动面
- 轴承孔
- clearance holes
- 装饰性边缘
- non-critical outer profiles
- reference dimensions
- assembly-critical dimensions
- inspection-critical datums
This helps the supplier control cost and focus inspection effort where it matters.

Clamping and Fixturing for Delrin Parts
Delrin is stiffer than PTFE, but it can still move under clamping force.
If the fixture squeezes the part too hard, the machined dimension may change after the part is released.
Common fixturing risks include:
| Fixturing Issue | 可能的结果 |
|---|---|
| Excessive vise pressure | Size shift or slight distortion after unclamping |
| Small contact area | Local marks or dents |
| Poor support under pockets | Chatter or uneven wall thickness |
| Thin walls unsupported | Wall deflection during finishing |
| Hard jaws on cosmetic surfaces | Visible surface marks |
| Poor support during drilling | Exit burrs or breakout |
| 材料去除不平衡 | Warping or flatness change |
For Delrin parts, the supplier may review soft jaws, 定制固定装置, low clamping pressure, larger contact areas, and staged machining when required.
The fixture should match the part function.
A simple block may not need special fixturing. A thin-walled Delrin housing, long sleeve, or precision bushing may need more careful support.
CNC Milling Delrin Parts
CNC milling is commonly used for Delrin plates, blocks, 外壳, 插槽, 口袋, 封面, 指南, 固定装置, and custom mechanical parts.
Delrin usually mills well with sharp tools and a stable cutting strategy.
Milling review may include:
- cutter sharpness
- 排屑
- 口袋深度
- 拐角半径
- wall height
- 表面饰面
- 毛刺控制
- thin feature support
- toolpath direction
- roughing and finishing allowance
- clamping contact areas
- final inspection condition
Delrin can produce clean surfaces, but dull tools, 热量积聚, or poor chip removal can still create poor edges, smeared surfaces, or burrs.
For milled Delrin parts, deep pockets and thin walls should be reviewed before quotation.
For service capability, 看看我们的 数控铣削服务 页.
CNC Turning Delrin Parts
CNC turning is often used for Delrin bushings, 袖子, 滚筒, 戒指, 垫圈, 垫片, 轴, and valve-style components.
Turning Delrin can produce clean round parts, but round features still need review.
Common turning risks include:
- jaw marks
- ovality
- 锥度
- bore size variation
- parting burrs
- thread burrs
- thin-wall distortion
- 表面痕迹
- poor concentricity
- inspection variation
For Delrin sleeves and bushings, the supplier should review the relationship between outer diameter, 内径, 壁厚, and chucking method.
A thick bushing may be stable. A long thin sleeve may need soft jaws, 支持, 轻加工切削, or modified inspection planning.
For rotational custom parts, 看看我们的 数控车削服务 页.
Delrin Threads Need Design Review
Delrin can be threaded, but plastic threads should not always be treated like metal threads.
Thread strength depends on:
- 螺纹尺寸
- engagement length
- 螺纹深度
- mating material
- 装配扭矩
- repeated assembly
- wall thickness around the thread
- insert requirement
- 毛刺控制
- 检查方法
Possible Delrin thread issues include:
| Issue | 为什么会发生这种情况 |
|---|---|
| Weak internal thread | Short engagement or small thread size |
| Thread burrs | Dull tool, poor entry or exit control |
| Stripping | High torque or metal screw overload |
| Cross-threading | Soft material and poor starting alignment |
| Size change | Tapping pressure or material recovery |
| Cracking around boss | Thin boss wall or sharp internal corners |
| Gauge variation | Thread gauge force and plastic flexibility |
For repeated assembly, the supplier may review metal inserts, larger threads, longer engagement, or lower assembly torque.
A drawing note such as “M3 thread” may not be enough when the thread carries load or is assembled many times.
Delrin Bushings, 袖子, and Sliding Parts
Delrin is commonly used for bushings and sliding parts because it has good low-friction behavior and useful wear properties in selected applications.
然而, a Delrin bushing is not only a simple round part.
The supplier should review:
- bore diameter
- 壁厚
- length-to-diameter ratio
- mating shaft material
- clearance fit
- running speed
- load direction
- 润滑条件
- 温度
- expected wear
- 检查方法
- surface direction
A tight bore tolerance may be reasonable for a thick, short bushing.
The same tolerance may be risky for a long, 薄的, unsupported sleeve.
For sliding parts, the drawing should define whether the surface is functional. Surface direction, 工具痕迹, and burrs can affect friction and assembly behavior.
Gears and Precision Mechanical Features in Delrin
Delrin is often used for gears, cams, 滚筒, 及精密机械零件.
These features need more review than simple plates.
For Delrin gears or moving components, the supplier may review:
- bore datum
- tooth form
- tooth burrs
- 跳动
- 同心度
- mating gear material
- backlash
- hub thickness
- shaft fit
- 检查方法
- 生产数量
- wear condition
A gear drawing should clearly identify which features control function.
The bore, tooth profile, and mating relationship may matter more than the outer cosmetic shape.
If a buyer only sends a 3D model without a 2D drawing, the supplier may not know which dimensions are critical.
Snap Fits and Flexible Features
Delrin can be used for clips, latches, and snap-fit parts, but these features need design review.
Snap-fit performance depends on:
- arm thickness
- root radius
- flex direction
- 装配力
- repeated use
- 边缘条件
- notch sensitivity
- 材料等级
- molding vs machining direction
- 表面划痕
- 工作温度
Delrin can also be sensitive to sharp internal corners in bending, 影响, or repeated assembly applications. A sharp milled corner can act as a stress riser, especially at the root of a snap-fit arm, internal pocket, latch, clip, or thin flexible feature.
For Delrin snap-fit arms and flexible features, the supplier should review internal corner radius, 工具痕迹, 边缘条件, part orientation, and repeated assembly requirement. A larger internal fillet radius may help reduce local stress concentration and improve the chance of stable long-term use.
The goal is not to make every Delrin corner large. The goal is to avoid placing a sharp machined corner exactly where the part needs to flex or absorb load.
Machined snap-fit features may not behave exactly like molded snap fits.
A machined sharp internal corner can increase stress concentration. A burr or tool mark near the root may reduce reliability.
For snap-fit Delrin features, the drawing should define whether the feature is functional, how often it is assembled, and what load or deflection it must survive.
Moisture and Temperature Effects
Delrin generally absorbs less moisture than nylon, but it is not completely unaffected by environment.
For most normal CNC applications, Delrin is a relatively stable plastic. 然而, parts with tight dimensions, long storage, changing humidity, or precision fits may still need environmental review.
Temperature can also affect dimensions.
A Delrin part measured immediately after machining may not be in the same condition as the part during final use.
The supplier may review:
- inspection temperature
- cooling time after machining
- 储存条件
- 湿度暴露
- assembly environment
- 工作温度
- mating material expansion
This does not mean every Delrin part needs special conditioning.
It means tight-tolerance plastic parts should be reviewed under realistic use and inspection conditions.
毛刺和边缘质量
Delrin usually cuts cleaner than many soft plastics, but burrs can still appear.
Burrs are common around:
- 钻孔
- milled slots
- 线程启动
- 薄边
- gear teeth
- parting faces
- pocket exits
- small internal corners
Burr control depends on:
| 因素 | 为什么它很重要 |
|---|---|
| 刀具锋利度 | Dull tools push and smear plastic |
| Feed and speed | Poor cutting conditions can create rough edges |
| Drill exit support | Unsupported exits can break out or burr |
| 刀具路径方向 | Exit direction affects burr location |
| Edge radius | Sharp edges are more burr-sensitive |
| Deburring method | Aggressive deburring can damage functional edges |
| Surface requirement | Cosmetic or sliding surfaces need extra care |
A drawing should mark burr-sensitive edges when they affect assembly, 密封, 滑动, 或外观.
For more on burr and edge quality, 看看我们的 What Is Deburring? CNC Edge Quality, Burr Removal, 及检验 指导.
Surface Finish for Delrin CNC Parts
Delrin can produce good machined surfaces, but surface finish should still match the part function.
A surface finish requirement may be important for:
- 滑动接触
- low-friction movement
- 衬套
- 齿轮
- guide surfaces
- 化妆脸
- sealing or contact faces
- visible customer-facing parts
Surface finish depends on:
- 工具锋利度
- 进给率
- cutter path
- 工具痕迹
- 材料等级
- 夹紧稳定性
- 芯片控制
- post-machining handling
- 检验标准
A note that only says “smooth finish” may not be enough.
Better drawing notes may say:
- which surfaces are visible
- which surfaces are sliding
- whether tool marks are acceptable
- whether Ra value is required
- whether scratches are allowed
- whether deburring must avoid rounding a functional edge
For broader finish planning, 看看我们的 CNC 表面处理指南.
Inspection Challenges for Delrin CNC Parts
Delrin inspection is usually easier than PTFE inspection, but it still needs proper planning.
Plastic parts can be affected by:
- measurement force
- part support
- 温度
- 湿度
- clamping history
- thin-wall flexibility
- thread gauge force
- bore gauge pressure
- 基准选择
- cosmetic surface handling
Inspection should focus on function.
A CMM report may be useful for some Delrin parts, but not every feature needs CMM inspection.
For critical Delrin parts, 定义:
| 特征 | Inspection Review |
|---|---|
| Precision bore | Bore gauge method, 圆度, and inspection pressure |
| Gear bore | 同心度, 跳动, and datum |
| 滑动面 | 表面光洁度, 毛刺, and flatness |
| 线 | Gauge method and assembly check |
| 薄壁 | Final inspection after unclamping |
| Snap feature | Visual check and functional fit |
| Critical hole pattern | Datum references and position tolerance |
| Cosmetic surface | Visual standard and handling marks |
For inspection planning, 看看我们的 CMM inspection for CNC parts 指导.
Delrin vs PTFE, 尼龙, 和窥视
Delrin is often compared with PTFE, 尼龙, and PEEK because all four are common engineering plastics.
| 材料 | Main Strength | 主要风险 |
|---|---|---|
| 德尔林 / 聚甲醛 | 良好的机械加工性, 低摩擦, 尺寸稳定性 | Grade confusion, 毛刺, 线程, 压配合, and temperature effects |
| ptfe | Very low friction, 耐化学性, 密封, 绝缘 | 低刚度, 蠕变, 夹紧变形, and inspection variation |
| 尼龙 | 韧性, 抗冲击性, 磨损行为 | 吸湿和尺寸变化 |
| 窥视 | High temperature, 力量, 耐化学性, premium performance | High material cost, 刀具磨损, grade-specific behavior |
Delrin is often a strong choice for mechanical plastic parts when the application does not require extreme temperature, 耐化学性, or ultra-low friction.
PTFE may be better for low-friction sealing and chemical resistance.
PEEK may be better for high-temperature and high-performance applications.
Nylon may be better for impact and toughness, depending on moisture and application conditions.
The best material depends on geometry, 加载, 温度, 化学暴露, 穿, 检查, 和成本目标.

Practical Drawing Notes for Delrin Parts
例子 1: Precision Bushing
Bore is functional sliding surface. Supplier to review bore size, 圆度, inspection pressure, and mating shaft fit before production.
This is better than only marking a tight bore tolerance.
例子 2: Delrin Thread
Internal thread is used for repeated assembly. Supplier to review engagement length, 配合螺丝, 毛刺控制, and assembly torque before machining.
This helps prevent treating plastic threads like metal threads.
例子 3: Gear Feature
Gear bore is datum-critical. Supplier to review bore-to-tooth relationship, 跳动, 毛刺控制, 及检验方法.
This helps protect functional motion.
例子 4: Snap-Fit Arm
Snap-fit feature is functional. Supplier to review root radius, 工具痕迹, 边缘条件, and repeated assembly requirement.
This reduces risk around sharp internal corners and stress concentration.
例子 5: 滑动面
Marked face is sliding surface. Supplier to review surface direction, 工具痕迹, 毛刺, and mating material before production.
This connects surface finish with the real part function.
Packaging and Handling for Delrin Machined Parts
Delrin is tougher than PTFE, but packaging still matters when the part has functional or cosmetic surfaces.
Packaging should be reviewed when the part has:
- 齿轮
- 线程
- polished faces
- 装饰表面
- 精密孔
- 滑动面
- snap-fit arms
- 薄边
- clean assembly requirements
Possible packaging steps include:
- individual wrapping
- soft separators
- avoiding heavy stacking
- protecting thin features
- separating metal and plastic parts
- keeping burr-sensitive parts separated
- protecting visible surfaces
- labeling critical faces if needed
Packaging does not improve machining quality, but it helps protect the condition achieved during machining and inspection.
