（1）PP Bumper Injection Mold Trial Process
● Mold Preparation: Securely close the mold to ensure it is properly aligned and ready for injection.
● Material Loading: Introduce dried plastic pellets into the hopper of the injection molding machine.
● Melting Phase: Heat the injection unit to melt the plastic pellets uniformly.
● Injection Phase: Inject the molten plastic into the mold cavity using a precision injection system.
● Pressure Maintenance: Apply consistent pressure to ensure the mold cavity is fully filled and maintains its shape during the filling process.
● Cooling Phase: Allow the injected plastic to cool and solidify within the mold, taking on the desired shape.
● Ejection: Carefully open the mold and eject the finished plastic product.

Q: Can you do the finished product or parts Only?
A: Sure, We could do finished product according the customized mold. And make the mold also.
Q: Can I test my idea/product before committing to mould tool manufacture?
A: Sure, we can use CAD drawings to make models and prototyping for design and functional evaluations.
Q: Can you do Assemble?
A: Of cause we could do. Our factory with assembly room.
Q: What shall we do if we do not have drawings?
A: Please send your sample to our factory,then we can copy or provide you better solutions. Please send us pictures or drafts with dimensions(Length,Hight,Width),CAD or 3D file will be made for you if placed order.
Q: What type of mould tool do I need?
A: Mould tools can be either single cavity (one part at a time) or multi-cavity (2,4, 8 or 16 parts at a time). Single cavity tools are generally used for small quantities, up to 10,000 parts per year whereas multi-cavity tools are for larger quantities. We can look at your projected annual requirements and recommend which would be best for you.
Q: I have an idea for a new product, but not sure if it can be manufactured. Can you help?
A: Yes! We are always happy to work with potential customers to evaluate the technical feasibility of your idea or design and we can advise on materials, tooling and likely set-up costs.
