FAQs of Large Size Injection Molding
What is considered "large size" injection molding?
Large size injection molding typically refers to parts with surface areas of 100 square inches or more. It generally requires injection molding machines with clamping forces of 500 tons or higher.
What are some key considerations for large size mold design?
Important factors include:
- Proper gating and runner system design
- Optimized cooling channels
- Structural reinforcement to prevent warpage
- Ejection system capable of handling large, heavy parts
- Venting to allow air to escape from large cavities
How do you determin the machine size needed for a large part?
A general rule of thumb is to use 2-8 tons of clamping force per square inch of part surface area. Other factors like wall thickness, part geometry, material viscosity, and mold temperature also influence the required clamping force.
What are the typical materials used in large-part injection molding?
Large-part injection molding often requires materials that can maintain their properties and structural integrity over larger surface areas and volumes. The typical plastic materials include:
- Polypropylene (PP)
- Polystyrene (PS)
- High-Density Polyethylene (HDPE)
- ABS (Acrylonitrile Butadiene Styrene)
- Nylon (Polyamide – PA)
- Acetal (Polyoxymethylene – POM)
- Polycarbonate (PC)
- Acrylic
