Types of Injection Molding

Plastic Injection Molding

Injection mold processing technology also has the characteristics of high efficiency, accuracy, strong applicability, short production cycle, etc. With the continuous development and innovation of science and technology, the efficiency of injection mold processing and the quality of finished products have been further improved.

Metal Injection Molding

Metal injection molding, abbreviated as MIM (Metal Injection Molding) This is a method of mixing metal powders and adhesives for injection molding. MIM is widely used in consumer electronics, auto parts, medical devices, power tools, industrial equipment and daily necessities. MIM can process metal data including low alloy steel, stainless steel, tool steel, nickel base alloy, tungsten alloy, hard alloy, titanium alloy, magnetic data, Kovar alloy, precision ceramics and so on.

Over Molding & Insertmolding

Over Molding is a kind of double injection molding process, which is usually formed by two kinds of plastic materials in two times, and the product is removed after the first injection molding, and then put into another set of molds or another cavity for the second injection molding.

What Is Used in Injection Molding?

Plastic injection molding involves injecting molten plastic into a mold cavity for mass production, where it cools and solidifies to form the desired shape. The choice of material greatly impacts the final product's strength, durability, and aesthetics. Essai commonly used materials in plastic injection molding:

1. Polypropylene (PP): Known for its versatility, PP is a widely used thermoplastic that offers excellent chemical resistance, low cost, and good impact strength.

2. Polyethylene (PE): PE is another popular thermoplastic with different variations, such as high-density polyethylene (HDPE) and low-density polyethylene (LDPE). It is known for its toughness, flexibility, and resistance to chemicals.

3. Acrylonitrile Butadiene Styrene (ABS): ABS is a commonly used engineering thermoplastic known for its high impact resistance, strength, and heat resistance. It is often used in automotive parts, electronic housings, and consumer goods.

4. Polycarbonate (PC): PC is a transparent and impact-resistant thermoplastic widely used in making safety glasses, electronic components, and automotive parts. It offers excellent optical properties, high heat resistance, and good dimensional stability.

5. Polyethylene Terephthalate (PET): PET is a versatile thermoplastic known for its excellent moisture barrier, clarity, and toughness. It is commonly used in packaging applications, such as bottles for beverages and personal care products.

6. Polyoxymethylene (POM): Also known as acetal or Delrin, POM is a high-strength thermoplastic with exceptional dimensional stability and low friction properties. It is often used in precision parts and gears.
