Thread un-winding/un-screwing mold structure is one of the art among all tools. It can be very tricky if without sufficient knowledge and experience in them. When part screws/threads are in outside, it is much easier to form; but for those parts with internal threads/screws, it can be challenge. Thanks to our partners in Israel and Switzerland, we have been accumulating abundant experience in designing and building tools for parts with both inside-screws/threads and outside-screws/threads. For some parts with low-depth thread in softer plastics like PP, PE, they are ok to be knocked out by force, or so called jump core. This is mostly popular in packing parts like various of caps. But for threads with depth of more than 2.5mm, un-winding/un-screwing system must be used. This is widely used for all industries like medical products, military defending products, electronics products, home appliances and Automotive parts. For us, it is a very essential knowledge and technology as a top-class tool manufacture, only in this way we can help customers from different industries. We have built tools of thread-parts in different plastic materials for small precision parts in medical products, for telecommunication products, for military defending products, for electronics products, for home appliance products and for automotive parts... Contact us to discuss more about this technology and we’d more than happy to share and learn about! How important a quality mold is for plastic injection molding mass production? So what would be happened if a mold maker uses cutting corners and shoddy methods to control material costs and processing costs just in order to improve their internal profits, instead of putting themselves into the mold users’ (mold buyers, customers’) shoes by considering injection molding production costs, product quality, and delivery time, Visual dynamics, and mold life? What serious consequences will this cause? The result will be very obvious without any doubt: After the mold is delivered to the customer, there will always be problems in the production and use process, which will cause the product to have quality problems, delays in delivery, increase in subsequent processes, waste of materials, etc., and even have to remake a new mold in order to ensure decent and efficient production, which the cost is extreamly high not just from money waste but more is the risk of losing customers’ trust with such poor quality product, poor delivery and service. However, after the delivery of the mold, there are also some mold users who cannot properly operating the mold during production, cannot give the mold proper maintenance, this could be also serverly damaging the mold and affecting molded products quality.
