Our certificates.
Is TPI IATF 16949 certified?
Yes. TPI is IATF 16949 certified by Bureau Veritas (certificate no. 0538209) for thermoplastic injection, and thermoset injection and compression moulded plastic components. We are also ISO 14001:2015 and ZED certified. You can view our certificates on our Quality page.
Do you design and build injection moulds in-house?
Yes. Our tool room designs, manufactures and maintains moulds in-house, building over 30 new moulds a year with an eight-week average lead time and 5-micron accuracy. We build hot and cold runner multi-cavity 2- and 3-plate moulds, plus soft tooling, using Moldex3D mould flow analysis, DFM and DOE.
What press sizes and materials can you mould (mold)?
We run 18 thermoplastic injection moulding machines from 50 to 650 tons, 4 thermoset injection presses from 88 to 160 tons, and 7 compression presses from 100 to 150 tons, with hot runner and mould temperature controllers, in a 45,000 sq ft plant. We process 40 material grades across 13 polymer families, including Nylon 6 and 6,6 (glass filled, UV and FR), PC, ABS, POM, PBT, modified PPE, HIPS, TPU, PP, LDPE, upcycled materials and phenolic and DMC thermosets.
Do you provide PPAP and automotive quality documentation?
Yes. We work to APQP and provide PPAP, PFMEA, SPC and process validation documentation, supported by an in-house quality lab with a vision measuring system, digital microscope, spectrophotometer and material testing equipment.
Do you export, and how do you ship?
Yes. Around 40% of our output is exported. Our plant near Chennai has access to the seaport and international airport, and we can ship anywhere in the world, including to 3PL warehouses.
Which industries do you supply?
Automotive, electrical, HVAC, home appliances, EV and defence. Customers include Ford Smart Mobility, Magna, ZF, Honeywell, Resideo, Parker Hannifin, GE and Lucas TVS.
