What are the commonly used injection molding materials?
Common injection molding materials include commodity plastics like PP, PE, ABS, and PS for general applications. Engineering plastics such as PA (Nylon), POM, PC, and PBT offer higher performance. High-performance options include PEEK, PPS, and PEI. Flexible materials like TPE, TPU, and Silicone are used for soft-touch applications.
What are the tools used in moulding?
Injection mold manufacturing requires CNC machining centers for precision cutting, EDM (Electrical Discharge Machining) for complex cavities, wire cutting machines for intricate details, surface grinders for finishing, and drilling machines. Quality control tools include CMM (Coordinate Measuring Machines), calipers, micrometers, and optical inspection systems.
What are the seven basic components of injection molding?
The seven basic components are the mold base providing structural support, cavity and core forming the part shape, runner system delivering molten plastic, gate controlling material entry, cooling system regulating temperature, ejection system removing finished parts, and venting channels allowing air escape during injection.
What are ejector pins and their features?
Ejector pins are cylindrical rods that push molded parts out of the mold cavity after cooling. Key features include hardened steel construction for durability, precise diameter tolerances for smooth operation, various head styles for different applications, and heat-treated surfaces to resist wear. They must withstand repeated cycles without bending or breaking.
What is the typical tolerances for injection molded parts?
Standard injection molding tolerances range from ±0.05mm to ±0.10mm for most commercial applications. Precision molding can achieve tighter tolerances of ±0.01mm to ±0.03mm with proper mold design, quality materials, and controlled processing conditions. Tolerances depend on part size, material shrinkage, and geometric complexity.
Here are the industries for the parts you can see in different realm.
