Plastic Injection Molding Parts Manufacturer

Philpott Solutions Group Rubber & Plastics division specializes in plastic injection molding for small parts. 
Companies routinely turn to our company for diverse needs. Small part injection molding is a manufacturing method that involves producing small and intricate plastic parts through injection molding machines. This process is particularly suitable for the mass production of small, complex components with high precision and consistency. 
Here’s an overview of the key aspects and benefits associated with small part injection molding, especially when working with materials like ABS, Acetal (POM), Acrylic, Nylon, HDPE, LDPE, Polycarbonates, Polypropylene, Polystyrene, and PVC: 

Process Overview 

  1. Material Selection: 
  • The choice of material depends on the specific requirements of the part, including factors such as strength, flexibility, transparency, chemical resistance, and temperature stability. 
  • Common materials include ABS for its toughness, Acetal for low friction and wear resistance, Acrylic for optical clarity, Nylon for high strength and durability, HDPE/LDPE for flexibility, Polycarbonates for impact resistance, Polypropylene for chemical resistance, and PVC for its versatility. 
  1. Tooling and Mold Design: 
  • Tooling and mold design play a crucial role in small part injection molding. Precision molds are created based on the CAD (Computer-Aided Design) models of the desired part. 
  • The mold consists of two halves, an injection side, and an ejector side, and it must be designed to accommodate the specific characteristics of the chosen material. 
  1. Injection Molding Machine: 
  • The selected plastic material is heated to a molten state and injected into the mold cavity under high pressure. 
  • The injection molding machine is equipped with a screw or plunger that pushes the molten material into the mold. 
  1. Cooling and Solidification: 
  • After injection, the mold is cooled to allow the plastic to solidify and take its shape. 
  • Cooling time is carefully controlled to ensure proper part formation and minimize production cycle times. 
  1. Ejection and Finishing: 
  • Once the plastic has solidified, the mold is opened, and the finished part is ejected. 
  • Secondary processes like trimming, machining, or surface finishing may be applied to meet specific design requirements. 

Benefits of Using a Plastic Injection Molding Parts Manufacturer like Philpott Rubber & Plastics 

  1. High Precision and Consistency: 
  • Injection molding ensures high precision, repeatability, and consistency in producing small parts with intricate details. 
  1. Cost-Efficiency for Mass Production: 
  • Once the molds are created, the cost per unit decreases significantly with higher production volumes and repeat orders. 
  1. Wide Range of Material Options: 
  • We support a variety of materials, providing flexibility to meet diverse application requirements.  
  1. Complex Geometry and Design Flexibility: 
  • Injection molding allows for the production of complex and detailed parts that may be challenging or costly using other manufacturing processes. 
  1. Short Production Cycle: 
  • Processes are generally fast, enabling a high production output in a relatively short amount of time, especially with reorders. 
  1. Reduced Material Waste: 
  • The process minimizes material waste, as excess material can be recycled and reused. 
  1. Scalability: 
  • Injection molding is easily scalable, making it suitable for both small and large production runs. 
  1. Durability and Strength: 
  • Depending on the material used, injection-molded parts can exhibit excellent durability, strength, and resistance to various environmental factors. 

By leveraging the expertise of a plastic injection molding parts manufacturer like our company, businesses can take advantage of these benefits to efficiently produce high-quality small plastic components for a wide range of applications.
