3. Cov pwm kub siab dhau lawm

1. Txhim kho qhov tso tawm ntawm cov pwm

2. Ua kom cov pa tawm ntau ntxiv

3. Txo cov pwm kub

Teeb meem ua rau thiab kev daws teeb meem

Adhesive pwm (khoom siv los yog khoom adheres rau saum npoo ntawm pwm, ua rau lub zos roughness ntawm cov khoom)

1. Kev kho tsis txaus thiab pwm kub tsis zoo

2. Cov khoom siv ntau dhau shrinkage tus nqi

3. Tsis sib npaug ejection ntawm tus pas nrig ejection

4. Qhov kub tsis zoo ntawm cov khoom embedded

5. Qhov saum npoo ntawm cov pwm tsis du thiab huv

1. Ua kom lub sijhawm curing thiab kho pwm kub

2. Kho tus nqi shrinkage ntawm cov khoom

3. Xyuas seb lub ejector pas nrig ntawm cov pwm yog tib yam

4. Ua kom zoo preheating ntawm inserts

5. Ua kom lub ntsej muag smoothness ntawm cov pwm

Blistering, bubbling

(Qhov saum npoo ntawm cov khoom protrudes tom qab demolding.)

1. Cov pwm kub qis dhau lawm thiab kev kho tsis txaus

2. Muaj dej noo hauv cov khoom
