Prepare a representative molding trial

Share the drawing, minimum wall thickness, gate arrangement, existing material and surface acceptance criteria. Record drying, machine settings and conditioning when evaluating samples. Confirm electrical readings at agreed locations; a change in mold or process may require another part-level check.
Discuss your application

Approve the part before production supply

Review dimensions, appearance, mechanical performance and the specified electrical or flame test together. Confirm the current TDS revision and supply terms for the accepted formulation.

Processing questions

Readings changed after a mold replacement

Injection molding
What to check

Repeat the test at the same contact points and under the same conditioning. Compare mold revision, gate, cooling and recorded settings. Review actual measurements before attributing the change to a material or setting.

Useful records

Part drawing, lot, tool revision and before/after readings in the same unit.

A molded part shows a surface mark

Injection molding
What to check

Locate the defect on the part drawing. Compare the original and revised parts under the same lighting and check what changed in the color package, tool or process.

Useful records

Photographs, cavity, color package and the inspection procedure.
