Why Teresi is a manufacturer, not a pure trader
A trader resells what others make. Teresi runs its own compounding lines and profile extrusion, and carries the full chain from resin to machined part. That means we control the grade recipe, the dimensional tolerance and the traceability — and we can start or stop at any single step you need.
Four integrated capabilities: one delivery chain from resin to finished part
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.
Materials we cover: two main lines + supporting supply
| Tier | Materials | Forms we supply |
|---|---|---|
| Specialty high-temperature engineering plastics (main line) | PEEK, PI, PEI, PPS, PSU/PPSU, PAI, PES, LCP, PA46/PA9T/PPA | Modified compounds, sheet, rod, tube, film, profiles, machined parts |
| Fluoropolymers (main line) | PTFE, PVDF, PFA, FEP, ETFE | Resin, sheet/rod/tube/film, filled compounds, high-purity parts, welded structures |
| General engineering plastics (supporting supply) | PA, PC, POM, ABS, PBT, PET, TPU, UHMWPE | Profiles, modified compounds, injection and machined parts for one-stop purchasing |
How the four capabilities combine
| Capability | What we do | Output |
|---|---|---|
| Resin supply | Imported + domestic specialty & fluoropolymer resins, by spec & duty | Resin/granule, plate/rod/tube/film blanks |
| Compounding | Reinforcement, wear, conductive/ESD, FR, food/medical grades | Modified compound granule, custom masterbatch |
| Profile manufacturing | Continuous extrusion of plate, rod, tube, film, custom profiles | Extrusion lines, compression plate, welding rod |
| Machining & molding | CNC/carving/compression/injection/welding to drawing | CNC center, carving, injection, welding equipment |
Who it fits
Best for buyers who need specialty high-temperature or fluoropolymer parts and want one manufacturer to handle modification, profiles and machining; for non-standard parts and drawing-based work; for prototyping and short runs where lead time matters; and for unified, traceable, locally-responsive sourcing.
Frequently asked questions
Are you a manufacturer or a trader?
We are a manufacturer focused on specialty high-temperature engineering plastics and fluoropolymers, with our own compounding lines and the four integrated capabilities (resin supply, compounding, profile manufacturing, machining) — not a pure trader.
Must I use all four capabilities together?
No. You can buy resin or profiles alone, or commission only compounding or machining. The four capabilities can be used separately or carry a part from raw resin all the way to a finished component within one loop.
How do you distinguish imported brands from your own modified compounds?
We clearly separate agency-imported grades from self-produced modified compounds and never present an agency grade as our own resin; during selection we state the source per duty and compliance.
Can you make a single prototype?
Yes. Standard-family plate/rod machined parts support single-piece prototyping and low-volume trial runs; lead time depends on material stock and process.
