TPI is one of the prominent plastic injection moulding companies in India that caters to the automotive, electrical, appliance and renewable energy industries. Injection Moulding is one of TPI’s primary services. With the combined power of cutting-edge machinery and high-end technology, TPI exceeds customer expectations in terms of quality and delivery time.
The infrastructure of TPI’s plastic injection moulding manufacturing unit includes 14 high-precision, conventional injection moulding machines with a range varying from 50 tons to 650 ton. All machines are supplemented with hopper driers, temperature controllers and hot runners. TPI believes in implementing reliable injection moulding principles with a professionally experienced crew. The facility is equipped to cater to injection moulding production 24/7 throughout the year.
The type of moulding process depends on the product. The purpose of the product, its design, budget and the expected production cycle will influence the moulding process. Parts that require complex and intricate shapes and require a large volume of repeatable processes are an ideal candidate for injection moulding.
The plastic mould is first inserted into the injection moulding machine and fitted into the clamping tools, which will keep the mould in place and closed. Plastic granules or pellets are injected into the moulding machine. The injected plastic is heated to form liquid plastic. The molten plastic is fed into the clamped mould using pressure. The liquid inside the mould undergoes a cooling process to solidify the plastic component, ready for use.
Thermoplastic is the most common type of plastic used in the injection molding process. Thermoplastic is a polymer that can easily be molded and solidified at extreme temperatures.
The production duration for building molds depends on the specific needs of the final part. We use P20 or C45 steel tooling to make molds that are required for short term use. Molds are also made for manufacturing millions of components. Our custom tooling process can manufacture the most complex tools within a limited duration.
In overmolding, two different plastic materials are molded together to produce a plastic product with the right texture and density. Usually, a soft plastic material like TPR/TPE/TPU is molded with another rigid plastic material like ABS.
