The Injection Molding Process Explained
Material Selection
The process begins with carefully selecting the appropriate plastic resin based on the product's requirements, such as strength, flexibility, heat resistance, and chemical compatibility.
Mold Design & Creation
A precision mold is designed using CAD software and machined from steel or aluminum. The mold consists of two halves that form the cavity and core of the desired part.
Injection
The plastic resin is fed into a heated barrel, melted, and injected into the mold cavity under high pressure. This ensures the material fills every corner of the mold.
Cooling & Solidification
The mold is cooled, allowing the plastic to solidify into the shape of the cavity. Cooling channels within the mold help regulate temperature and ensure uniform solidification.
Ejection & Finishing
The mold opens, and ejector pins push the finished part out. Any excess material, such as sprues or runners, is trimmed, and the part undergoes quality inspection and finishing processes.
Advanced Injection Molding Technologies
Modern injection molding manufacturers employ a range of advanced technologies to enhance efficiency, precision, and sustainability. These include:
- Multi-material molding for complex, multi-color parts
- Micro molding for tiny, high-precision components
- Insert molding for combining plastic with metal or other materials
- Gas-assisted molding for reducing part weight and improving strength
- Automated quality control systems using AI and machine vision
