Many things in our lives are produced by литье под давлением. Процесс литья под давлением позволяет быстро производить множество деталей.. Many people know little about it. Сегодня, Rapidefficient will share with you what injection molding is and what are the commonly used materials.
Что такое литье под давлением?
Injection molding is a method of injecting heated and molten materials into a mold using high pressure, and then cooling to obtain a molded product. This method can quickly and mass-produce many parts with complex shapes, and is one of the mainstream processing methods.
After understanding the principle, Rapidefficient will tell you about the entire production process, which can be roughly divided into the following 6 stages.
1: Mold closing
The prepared molds are combined with tools to prepare for injection molding.
2: Инъекция
The high-temperature molten material is injected into the mold.
3: Pressure holding
Maintain pressure to allow the molten material to fill the entire mold without any gaps.
4: Охлаждение
Let the heated solution cool and form.
5: Mold opening
Open the mold and take out the product
6: Отделка
Finish the molded product.
Common materials for injection molding
Injection molding uses a wide range of materials. Today Rapidefficient selects 10 common materials to explain.
1: Акрил
Acrylic has good mechanical strength, is lightweight, and has a clear, transparent appearance. Although it has no ductility, it has good resistance to chipping.
2: АБС
ABS has good strength and toughness, impact resistance, and chemical resistance to acids, щелочи, and oils.
3: Nylon polyamide
Nylon is an excellent material with high toughness, термостойкость, and surface friction/wear properties.
4: Поликарбонат
Polycarbonate has excellent toughness, chip resistance, and impact resistance.
5: Polyoxymethylene
Polyoxymethylene is known for products that require high precision. Due to its stiffness and rigidity, it has good dimensional stability.
6: Полипропилен
Polypropylene is hard, heat-resistant, chemically resistant, and can be recycled many times.
7: Полистирол
Polystyrene is particularly lightweight, resistant to moisture and chemical reactions, and is well suited for injection molding due to its uniform heat shrinkage within the mold.
8: полиэтилен
Polyethylenes are ductile, have good impact strength, and are resistant to creep (can withstand mechanical loads for a long time without deforming). Кроме того, they are resistant to chemical reactions.
9: Thermoplastic Elastomers
Thermoplastic elastomers are a plastic-rubber mixture. They can be stretched to great lengths, are strong, and are recyclable.
10: Thermoplastic Polyurethanes
Thermoplastic polyurethanes are another rubber-plastic mixture whose polyurethane component has very desirable qualities. It is very hard and has very good compressive strength, abrasion resistance, и химическая стойкость.
The above 10 materials are commonly used materials.Of course, there are many other materials. As a professional обработка с ЧПУ manufacturer, Rapidefficient has a wide range of materials for injection molding. It can match materials according to customer needs and help customers turn ideas into reality.
