隔离墩模具***是热固性塑料模具的型腔部分大都必须进行热处理。这就要求钢材具有较好的淬透性和很小的变形。一般热塑性塑料成形用模具,采用调质、预硬化等处理即可。而热固性塑料成形用模具则必须淬硬。钢模具的凹型腔时常采用放电加工,放电加工后表面的硬化层要浅,以便于抛光。抛光在隔离墩模具的型腔加工中是耗时间的。时间长则增加成本。目前对自动抛光的技术尚未达到实用阶段,仍然以手工抛光为主。硬化层厚则抛光工时增大。
MOST OF THE CAVITY MOLD OF THE ISOLATION PIER, ESPE***LLY THE CAVITY OF THERMOSETTING PLASTIC MOULD, MUST BE HEAT TREATED. THIS REQUIRES THAT THE STEEL HAS GOOD HARDENABILITY&VERY LITTLE DEFORMATION. THE MOULD FOR GENERAL THERMOPLASTIC FORMING CAN BE TREATED BY QUENCHING&TEMPERING, PRE HARDENING&SO ON. THERMOSETTING PLASTIC FORMING DIES MUST BE HARDENED. THE CONCAVE CAVITY OF THE STEEL MOULD IS OFTEN DISCHARGED BY EDM,&THE HARDENED LAYER ON THE SURFACE AFTER DISCHARGE IS SHALLOW SO AS TO BE EASY TO POLISH. POLISHING IS THE MOST TIME-CONSUMING IN THE CAVITY MOLD PROCESSING OF THE ISOLATION PIER. LONGER HOURS INCREASE COSTS. AT PRESENT, THE AUTOMATIC POLISHING TECHNOLOGY HAS NOT YET REACHED THE PRACTICAL STAGE, BUT STILL MAINLY MANUAL POLISHING. WHEN THE HARDENED LAYER THICKNESS IS INCREASED, THE POLISHING TIME IS INCREASED.
国产隔离墩模具***满足率一直不足74%,其中大型、精密、长寿命模具满足率***。目前工业发达的模具正在加速向转移,国际采购越来越多。市场需求旺盛,生产发展一时还难以跟上,***的局面还将持续一段时间。注塑模具企业不但要重视产品的研发,同时更要重视产品的***。只有企业在技术人才、技术***方面要具有***的实力,同时能够在***时间内准确把握客户的个性化需求,企业才能稳定飞速的发展。
THE DOMESTIC MARKET RATE OF ISOLATING PIER MOLD HAS BEEN LESS THAN 74%, OF WHICH THE LARGE, PRECISION, LONG LIFE MOLD MEETS LOWER RATE. AT PRESENT, THE MOLD OF INDUSTRIAL DEVELOPED COUNTRIES IS ACCELERATING TO TRANSFER TO CHINA, MORE&MORE INTERNATIONAL PROCUREMENT. MARKET DEMAND IS EXUBERANT, PRODUCTION DEVELOPMENT IS HARD TO KEEP UP WITH, THE SITUATION OF SHORT SUPPLY WILL CONTINUE FOR A PERIOD OF TIME. THE INJECTION MOLD ENTERPRISE SHOULD NOT ONLY PAY ATTENTION TO PRODUCT R & D, BUT ALSO PAY MORE ATTENTION TO PRODUCT INNOVATION. ONLY ENTERPRISES IN THE TECHNICAL PERSONNEL, TECHNICAL INNOVATION SHOULD HAVE A STRONG STRENGTH,&AT THE SAME TIME IN THE FIRST TIME TO ACCURATELY GRASP THE INDIVIDUAL NEEDS OF CUSTOMERS, ENTERPRISES IN ORDER TO STABLE&RAPID DEVELOPMENT.
