Injection molding is one of the leading processes for manufacturing plastics. It is widely used for mass-producing identical parts with tight tolerances. It is a cost-effective and extremely repeatable technology that yields high-quality parts for large series production. It is a fast, intensive process where high heat and pressure are involved to inject molten material [...]
Mold builders encounter many challenges when deep-hole drilling, including hole straightness, poor cutting tool life and excessive time spent in the hole. Troubleshooting these challenges requires a look at correct coolant flow, pressure and chip evacuation but begins with understanding the limitations of the cutting tools, toolholders and machines. Time—whether spent in the hole, changing [...]
Proper mold venting is essential for producing quality parts. During the molding process, the air contained in the mold needs a way to escape, otherwise the melt will compress and trap that air in the cavity. A combination of melt pressure and high temperature will then ignite the oxygen (called the “diesel effect”), causing burnings [...]
Everyday mold builders face various challenges as they tackle each new mold project that enters the shop. Whether it involves engineering, building, maintaining, or repairing molds, this industry’s dedicated technology suppliers offer solutions. Here are some insights and instructions to help your team through four specific challenges. 1） How to Reduce Risk in Plastic Part [...]
1. Control Your Molds Far too many companies that have their products made overseas wrongly assume they will own the molds and the accompanying IP used to make their products. If you do not pay for your molds upfront and have a contract that both works for the country in which your molds are being [...]
If you have been considering sourcing to injection mold makers China, you probably know that it isn’t nearly as easy or straightforward an endeavor as it sounds. There are several ways to establish a provider, a number of different aspects to consider before making your final selection, and a variety of negotiations that need to [...]
Metrology is an enabling technology and today’s options provide invaluable insight concerning the demands of micro-size tooling and parts. Metrology equipment and skills are used to measure steel details in the mold, part features/dimensions to ensure the parts meet print tolerance and to guarantee a capable process. Typically, shops use high-end optical white light interferometer-based [...]
Mold manufacturing is an increasingly challenging industry. Whether you have pivoted to supplying the medical industry or are a longtime automotive mold/die producer, you have probably seen where the market is heading. Parts and designs are getting more complex. Customers are pushing for shorter production times. Molds require greater degrees of precision and exact surface [...]
When taking on a tooling project, no detail can be overlooked. With the numerous variables that can impact production, you should expect some hiccups. That is why mold flow analysis is such a crucial component of production. Let’s dive into this idea and see how to manage the risks associated with designing a new mold. [...]
Molds in production often have various core pull side-actions, while designed with the best of intentions, do not fulfill current needs. Different materials, new molding parameters, requirements to drive glass below the surface or simply under-designing for the application, are just a few of the many reasons why mold performance suffers, often resulting in a [...]
