Insufficient welding/weld strength of methyl styrene-acrylonitrile copolymer products
문제 현상
After products are connected by hot plate welding, ultrasonic welding, etc., the welding strength is insufficient, and they break from the weld under stress.
원인 분석
(1) Welding temperature too low, material not fully melted and fused
(2) Insufficient welding pressure or time too short
(3) Welding surface contaminated (oil, dust, etc.)
(4) Material moisture content or additives affect welding
(5) Welding surface not flat, insufficient contact area
해결 방법
(1) Optimize welding temperature to the appropriate range for methyl styrene-acrylonitrile copolymer
(2) Increase welding pressure and time
(3) Clean the welding surface before welding
(4) Fully dry raw material, reduce additive dosage
(5) Ensure the welding surface is flat
핵심 요약
Welding strength is determined by melt fusion quality.
