Injection Molding
Tooling and molding for your repeat plastic parts.
YOUR SPECIFIED POLYMER. YOUR SUPPLY FORM. YOUR FINISHED PART.
Other Plastic Materials for Your Custom Parts
Review other plastic materials for your custom parts when your drawing calls for PET, PSU, PPSU, PAI, PI or PVDF. Share the full manufacturer product, stock or resin form, operating conditions and inspection needs before approving a material or manufacturing route.
Material availability and manufacturing scope are reviewed for your drawing.
Grade & FormSpecify stock or resin.
Exposure & AssemblyDefine media, load and temperature.
Stability & FitAgree the inspection state.
Material RecordsRetain grade and lot identity.
4 Material Groups to Review First
Start with the full manufacturer product and purchasing form. These are review directions, not interchangeable grades or stock promises.
PET / TECAPET stock
For your TECAPET custom machining quote or custom PET parts, identify the actual stock manufacturer, complete product, color and lot. PET-P machining stock and packaging PET resin are separate purchasing specifications.
PSU / PPSU products
For custom PSU parts or custom PPSU parts, keep the polymer identity and full product separate. A UDEL P1700 custom molding quote needs the exact UDEL P-1700 suffix and color; a RADEL R5500 custom machining quote also needs the actual stock-shape source.
PAI / PI stock
A TORLON 4203 custom machining quote, TORLON 4301 custom machining quote or TECASINT 2011 custom machining quote must retain the exact supplied product and condition. Polyimide machining concerns PI; TORLON is PAI. These names do not authorize substitution.
PVDF / KYNAR direction
For PVDF machining or custom PVDF parts, identify the actual stock product. A KYNAR 740 custom stock shape quote requires confirmation of the stock producer and its product evidence; the resin designation alone does not identify a purchased rod or plate.
Choose Around Your Part’s Requirements
Review PET / TECAPET stock for Your Drawing
For your TECAPET custom machining quote or custom PET parts, identify the actual stock manufacturer, complete product, color and lot. PET-P machining stock and packaging PET resin are separate purchasing specifications.

Compare the Specification Before the Property
Six polymer families. Exact product, purchasing form and application evidence govern your decision.
| Material reference | What must remain distinct |
|---|---|
| PET / TECAPET | Engineering PET stock family; full product, modification, color and lot remain necessary. |
| PSU / UDEL P-1700 | Polysulfone product family; retain full suffix, color and supply form. |
| PPSU / RADEL R-5500 | Polyphenylsulfone product; distinct from PSU and PPS. Confirm stock or resin route. |
| PAI / TORLON 4203 or 4301 | Polyamide-imide products; separate grade, formulation, condition and finishing requirements. |
| PI / TECASINT 2011 | Named polyimide stock product; not a TORLON PAI equivalent. |
| PVDF / KYNAR 740 | Resin reference; supplied stock identity and processing route require separate evidence. |
2 Purchasing Routes. Different Material Evidence.
Machining Stock: Full Product + Condition
For other plastic materials stock or resin grade traceability, retain the actual stock producer, complete product, color, dimensions, supplied condition and lot. A generic resin sheet cannot establish stock-shape identity.
Resin: Exact Grade + Approved Process
Share the full manufacturer resin, suffix, color, molding or forming route, quantities and sample acceptance. Confirm current product handling and processing instructions; a family listing does not establish LK manufacturing availability.
Resolve 6 Material Risks Before Production
Material identity for Your Finished Part
Can PET-P stock be replaced with packaging PET resin? Do not assume equivalence. Confirm the specified engineering stock product, manufacturing form, traceability and approval against your drawing.
Stability & machining for Your Finished Part
Review support, machining sequence, heat history and any supplier-specified conditioning with the actual stock product. Agree the final inspection state before comparing dimensions.
Wear & mating parts for Your Finished Part
Can TORLON 4301 replace TORLON 4203 in machined parts? No automatic substitution is assumed. Compare exact-grade data, mating material, load, speed, lubrication and approved functional samples.
Media & temperature for Your Finished Part
Identify chemicals, concentration, temperature, exposure time and load together. A PVDF or sulfone family name does not establish resistance or cleaning-cycle life for a finished assembly.
Heat treatment & finishing for Your Finished Part
Does PAI stock need post curing after machining? Obtain current instructions from the actual stock supplier for its product and supplied condition. Do not apply a universal cycle to every PAI or PI part.
Finished inspection for Your Finished Part
Other plastic materials finished part inspection requirements should define datums, critical fits, support, surface condition and measurement environment. Material documents and functional approval serve separate purposes.

Agree 3 Checks for Your Receiving Team
| Your check | Evidence to agree |
|---|---|
| 1 | Manufacturer, full grade and suffix, modification, color, supply form, supplied condition and lot. |
| 2 | Controlled drawing, critical fit, datums, support, edge quality and agreed measurement state. |

Answers Before You Specify
How should a specified plastic grade be quoted if it is not listed?
Send CAD and controlled drawing, manufacturer, full grade and suffix, color, supply form, quantities, application conditions and required evidence. Availability and manufacturing scope require project confirmation.
Are PSU, PPSU and PPS the same material?
No. They are different polymer families. Preserve the actual product name and supply form; do not approve substitutions from similar abbreviations or appearance.
Can a resin datasheet identify a finished stock shape?
It cannot establish the identity of unspecified stock. Use documents for the actual stock producer, full product, modification, color, condition and lot.
Is TECASINT 2011 interchangeable with TORLON PAI?
No automatic interchangeability is assumed. TECASINT 2011 is a PI stock product and TORLON identifies PAI products. Compare exact product data, purchasing form, process and your functional approval.
What documents are needed to approve a special plastic grade?
Agree material identity and lot, current product data, supplied condition, controlled drawing, approved sample, dimensional inspection and any specified exposure or functional tests. Any regulated-use requirement needs exact product and application evidence.
How should I compare quotes for these custom parts?
Use the same drawing, material product, stock or resin route, quantity, sample approval, inspection and delivery scope. PET, sulfone, PAI, PI and PVDF references are separate candidates, not a common performance ranking.
Material references: Ensinger · Syensqo · Arkema. Candidate material families are not inventory or capability commitments.
Retain Your Complete Polymer and Product Name
PET, PSU, PPSU, PAI, PI and PVDF are separate polymer families. European trade names and generic abbreviations do not create an approved EN/DIN equivalent or substitution.
Stock and Resin References
TECAPET and TECASINT 2011 are named stock directions. UDEL P-1700, RADEL R-5500, TORLON 4203, TORLON 4301 and KYNAR 740 need their own full product and supplied-form review.
Confirm Your Evidence
Keep manufacturer data, stock-producer identity, supplied condition, lot and approved drawing together. No family-wide stock availability, regulated-use approval or process commitment is implied.
Manufacturer references: Engineering PET family and stock product identity → · Exact PSU product and suffix scope → · PPSU product family; separate from PSU/PPS → · PAI product identity; exact grade and stock evidence required → · Named PI stock; separate polymer from PAI → · Named PVDF resin and supported process boundary →
