Types of Plastics Used in Plastic Mold Factories

Exploring Common Types of Plastics Used in Plastic Mold Factories

Plastic mold factories are at the forefront of innovation in manufacturing, and the choice of materials is crucial to their success. In this article, we will delve into the common types of plastics used in plastic mold factories, with a particular focus on clear injection molded plastics, and understand how each type serves a specific purpose in the manufacturing process.

Acrylonitrile Butadiene Styrene (ABS)

ABS is a widely used thermoplastic in plastic mold factories due to its excellent impact resistance and durability. It is known for its ability to maintain its shape and integrity even at low temperatures, making it suitable for various applications, including automotive parts, consumer goods, and toys. While ABS is not typically transparent, it can be modified to enhance clarity for applications like clear injection molded plastics.

Polycarbonate (PC)

Polycarbonate is known for its exceptional optical clarity and high impact resistance, making it an ideal choice for clear injection molded plastics. It is commonly used in industries where transparency is crucial, such as electronics, medical devices, and automotive headlamp lenses. PC is also known for its resistance to heat and flame, adding to its versatility.

Polypropylene (PP)

Polypropylene is a versatile thermoplastic that is easy to mold and has excellent chemical resistance. It is commonly used in plastic mold factories for applications where chemical exposure is a concern, such as laboratory equipment and chemical containers. While PP is not known for its transparency, it can be modified to achieve a level of translucency suitable for certain applications.

Polyethylene (PE)

Polyethylene is known for its low cost and ease of processing, making it a popular choice for a wide range of applications. It is often used in plastic mold factories to produce items like bottles, containers, and packaging materials. While it is not typically used for clear injection molded plastics, it serves as a versatile material for various other molding needs.

Polyethylene Terephthalate (PET)

PET is a transparent thermoplastic known for its clarity and excellent barrier properties against moisture and gases. It is commonly used for clear injection molded plastics, particularly in the production of beverage bottles, food containers, and packaging materials. PET’s recyclability also adds to its appeal in sustainable manufacturing.

Polyvinyl Chloride (PVC)

PVC is a versatile thermoplastic known for its chemical resistance and flame retardant properties. While it is not typically used for clear injection molded plastics, it finds applications in a wide range of products, including pipes, fittings, electrical insulation, and automotive components. PVC’s adaptability and durability make it a valuable material in plastic mold factories.

The Role of Material Selection in Clear Injection Molded Plastics

Clear injection molded plastics require special attention to material selection to achieve the desired clarity and transparency. Polycarbonate (PC) and Polyethylene Terephthalate (PET) are among the top choices for applications where optical clarity is essential. These materials undergo specific processing techniques and quality control measures to ensure they meet stringent transparency standards.

Tailoring Plastics to Specific Needs

Plastic mold factories have the flexibility to tailor plastics to meet specific manufacturing requirements. Through additives and modifications, manufacturers can enhance properties such as clarity, UV resistance, flame retardancy, and impact resistance. This adaptability allows plastic mold factories to cater to a wide range of industries and applications.


The choice of plastics in plastic mold factories is a critical decision that directly impacts the quality, durability, and functionality of the final products. Each type of plastic serves a unique purpose, whether it’s the exceptional clarity of polycarbonate for clear injection molded plastics, the impact resistance of ABS, or the chemical resistance of polypropylene. With the right material selection and processing techniques, plastic mold factories can produce components and products that meet the diverse needs of various industries, driving innovation and efficiency in manufacturing.
