Q

TPE Dehumidifying Drying

A

Drying of overmolding material requires dehumidifying equipment; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a reference for troubleshooting similar problems in the future

Q

TPE Hardness-Graded Drying

A

TPE drying temperature is graded by hardness; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a reference for troubleshooting similar problems in the future

Material Drying TPE drying temperature hardness sticking

Q

TPE Drying Judgment

A

TPE drying is distinguished by grade type; overmolding material must be dried; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a reference for troubleshooting similar problems in the ...

Q

TPE Workshop Humidity

A

Seasonal quality fluctuations of TPE originate from ambient humidity; rainy season compensated drying plus workshop dehumidification keeps the weather out; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence

Material Drying TPE; plum rain; humidity; compensation; dehumidification

Q

TPE Overmolding Material Must Be Pre-dried

A

Pre-drying of TPE overmolding is the prerequisite for bonding quality; 80℃×2-4h is a fixed process for overmolding material; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence

Material Drying TPE; overmolding; pre-drying; 80℃; gas marks

Q

TPE Drying Graded by Hardness

A

TPE drying temperature must match hardness; soft material uses low temperature to prevent agglomeration, hard material uses high temperature to ensure drying, with graded management; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence

Material Drying TPE; drying temperature; hardness grading; 40-60℃; vacuum

Q

TPE Drying 0.1% Red Line

A

TPE drying is the guarantee of appearance quality; the 0.1% red line plus the heat-preserving hopper keeps moisture defects out before injection; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence

Material Drying TPE; drying; 0.1%; 80-100℃; bubbles

Q

TPE Silver Streak

A

Silver streak morphology is the key to cause judgment; check drying for U-shape, air for scattered, degradation for shiny; variable-by-variable verification locates the fastest.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Q

TPE Delamination (Moisture Type)

A

Moisture-type delamination and silver streaks share the same source; drying verification is the first troubleshooting action.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a troubleshoo...
