Choose TPE hardness from the function and molded geometry, then verify it on the finished part. A Shore value does not directly define stiffness, grip, sealing force, compression set or abrasion resistance, and a thin overmold can feel harder than a thick test plaque made from the same grade. What
When a mold trial sample comes back and it does not meet what you expected, you have a fixed sequence of steps that keeps the project moving without turning a normal correction cycle into a dispute. Hold the relevant production approval until the issue is settled. Verify the requirement you
SEBS, SBS, TPO, TPV and TPC are different thermoplastic elastomer families with different temperature, weathering, compression, processing and cost profiles. The right choice begins with service conditions and component function; the family name only narrows the search to exact grades. Family-level comparison Family What it is Typical selection strengths Limits
Design for end of life by choosing the intended recovery route before the material stack is frozen. Then reduce material variety, make incompatible components separable, provide accurate identification and verify compatibility with the actual collection and reprocessing system. Step 1: choose a realistic recovery route Possible routes include reuse/repair, remanufacture,
Send one controlled change package: updated CAD, a marked drawing and a short change record that identifies the part, current and new revisions, old and new requirements, reason, affected cavities, approval owner and required verification. This prevents verbal or chat instructions from becoming an ambiguous machining decision. “Communicate early” is
PLA and TPU can be mechanically recycled under controlled conditions, and both have chemical-recycling routes under development, but the feasible option depends on grade, additives, contamination, collection volume and local infrastructure. Laboratory depolymerization results do not prove that a mixed post-consumer part has a commercial recycling route. Why PLA and
A circular plastics program connects product life, material choice, factory yield, repair/reuse and a verified end-of-life route. Switching to a material labelled “green” without changing design, supply controls or recovery logistics is not a complete circular-economy strategy. Set a product-system objective Choose a measurable objective before choosing a resin: longer
Bio-based resins can reduce reliance on fossil feedstocks, but “bio-based,” “biodegradable” and “compostable” describe different attributes. None of those labels proves that a resin is suitable for an injection-molded product. Product teams still have to qualify heat resistance, impact, dimensional stability, moisture behavior, chemicals, appearance, processing, supply and the intended
Evaluate PLA and bio-based plastics for EV parts by heat, impact, moisture, aging, flammability, VOC, chemical exposure, molding and OEM validation.
You do not need to be a molding engineer to start an injection-molding project, but you do need a controlled sequence of decisions. Define what the part must do, prepare the best available CAD and requirements, get DFM feedback before tool release, and tie payments and approvals to clear deliverables.
Select high-performance injection plastics by service temperature, chemicals, wear, dimensional stability, flame, electrical needs, processing and total cost.
Compare ABS, PC, PLA, nylon and TPU for injection-molded parts by stiffness, impact, heat, chemicals, moisture, shrinkage, finish and processing risk.
Choose thermoset rubber or TPU by sealing, compression set, heat, abrasion, chemicals, geometry, tooling, production volume and lifecycle needs.
Compare TPU, the wider TPE family and TPC elastomers by abrasion, compression set, heat, chemicals, overmolding, processing and cost.
Structure an injection molding agreement around scope, tooling ownership, approvals, quality, changes, delivery, IP, warranty, transfer and dispute terms.
Compare PLA, PBS, PHB and starch-based plastics by feedstock, properties, molding behavior, durability, composting evidence and supply risk.
Compare PLA and PHA by stiffness, toughness, heat, moisture, injection molding, cost and verified composting or biodegradation conditions.
Compare ABS, PLA and PETG for 3D printing by heat, impact, moisture, fumes, ventilation, print behavior, durability and end-use validation.
