280 Comments / Industry Trends / By

As an injection mold factory with over 20 years of manufacturing experience, we understand the critical role that materials play in the injection molding process. The choice of mold raw materials can significantly impact the quality and performance of the final product. This article provides a comprehensive guide to mold raw materials used in injection molding production, including commonly used materials and their applications in daily life, automobile manufacturing, electronic products, medical equipment, and more.

Materials for Injection Molding:

There are several materials that can be used for injection molding production, including:

  1. Thermoplastics: Thermoplastics are the most commonly used materials for injection molding production. They are versatile, durable, and can be easily molded into complex shapes. Some common types of thermoplastics used in injection molding include polypropylene, polystyrene, and polyethylene.
  2. Thermosets: Thermosets are materials that cannot be remolded once they have been molded and cured. They are ideal for products that require high heat resistance, such as electrical components. Somecommon types of thermosets used in injection molding include epoxy resins and phenolic resins.
  3. Elastomers: Elastomers are materials that can be stretched and returned to their original shape. They are ideal for products that require flexibility and durability, such as seals and gaskets. Some common types of elastomers used in injection molding include silicone and rubber.
  4. Composites: Composites are materials that are made up of two or more different materials. They are ideal for products that require specific mechanical properties, such as strength and rigidity. Some common types of composites used in injection molding include carbon fiber-reinforced polymer and glass fiber-reinforced polymer.

Commonly Used Injection Molding Materials:

In the market, there are some commonly used injection molding materials, including:

  1. Polypropylene (PP): PP is a thermoplastic material that is commonly used in injection molding production due to its low cost, lightweight, and high chemical resistance. PP is widely used in the production of household appliances, automotive parts, and packaging materials.
  2. Acrylonitrile Butadiene Styrene (ABS): ABS is a thermoplastic material that is known for its strength, toughness, and heat resistance. It is commonly used in the production of electronic housings, automotive parts, and toys.
  3. Polycarbonate (PC): PC is a thermoplastic material that is known for its high impact resistance, transparency, and heat resistance. It iscommonly used in the production of automotive parts, electronic components, and medical equipment.
  4. Polyethylene (PE): PE is a thermoplastic material that is known for its flexibility, durability, and chemical resistance. It is commonly used in the production of packaging materials, pipes, and toys.

Application of Injection Molding Products:

Injection molding products have a wide range of applications in daily life, automobile manufacturing, electronic products, medical equipment, and more. Some examples of injection molding products include:

  1. Daily Life: Injection molding products are commonly used in household appliances, such as kitchenware, tableware, and bathroom accessories.
  2. Automobile Manufacturing: Injection molding products are widely used in the automotive industry, including parts such as dashboards, bumpers, and door handles.
  3. Electronic Products: Injection molding products are common in the production of electronic components, such as computer housings, phone cases, and battery covers.
  4. Medical Equipment: Injection molding products are widely used in the medical industry, including parts such as syringes, vials, and IV connectors.

In conclusion, the choice of mold raw materials is critical in the injection molding process, as it directly impacts the quality and performance of the final product. Understanding the different types of materials available and their applications can help manufacturers choose the right material for their injection molding production.
