Four integrated capabilities
One manufacturer, one closed loop — from raw resin to finished component. Each capability can be used on its own, or combined end-to-end:
1. Resin & raw-material supply
PEEK, PI, PEI, PPS and fluoropolymer (PVDF, PFA, FEP, PTFE) resins — imported and domestic grades, with sources clearly distinguished.
2. Compounding & modification
Glass/carbon fiber reinforced, wear-resistant, conductive/ESD (10^3–10^9 ohm), flame-retardant, custom colors, food- and medical-grade.
3. Profile manufacturing & supply
Continuous extrusion of sheet, rod, tube, film and custom profiles; standard stock plus non-standard sizes.
4. Precision machining & molding
CNC machining, carving, compression molding (sintering), injection molding and welding of non-standard parts to drawing.
What we make: two main lines + supporting supply
We center on two material lines and supply general engineering plastics as supporting materials for one-stop purchasing.
Specialty high-temperature engineering plastics
PEEK, PI, PEI, PPS, PSU/PPSU, PAI, PES, LCP, PA46/PA9T/PPA — modified compounds, stock profiles and machined parts.
Fluoropolymers
PTFE, PVDF, PFA, FEP, ETFE — resin, sheet/rod/tube/film, filled compounds, high-purity parts and welded structures.
Modified compounds
Reinforced, wear-resistant, conductive/ESD and food-/medical-grade compounds engineered to your duty cycle.
Custom profiles & machining
CNC machining, extrusion and welding of non-standard profiles, sheet, rod and tube to drawing.
General engineering plastics (supporting)
PA, PC, POM, ABS, PBT, PET, TPU, UHMWPE — supplied as ancillary materials to meet one-stop purchasing; not part of the core positioning.
Industries we serve
Semiconductor & electronics, photovoltaic, medical & life science, chemical & fluid handling, new energy, mechanical transmission & wear parts, and aerospace. We support material selection, prototyping and volume supply.
Why Teresi
We are a manufacturer with our own compounding and profile lines, not a pure trader: we control the grade recipe, tolerance and traceability. Six production lines in Suzhou and Changzhou, domestic-alternative selection for imported grades (e.g. Victrex PEEK), technical selection support, and compliance documentation on request.
