  Making high-quality plastic parts in a higher volume used to be challenging with traditional injection molding methods, especially involving cosmetic and medical products. These processes often resulted in quality and strength issues because the molten plastic would run off uncontrollably when injected from the barrel's nozzle. However, advancements in technology have led to the development of solutions like valve gates, effectively addressing this problem.   Valve gates are a type of hot runner gate equipped with a special valve or pin to control the flow of molten plastic into the mold. They are commonly used in hot runner systems to manage melt flow by controlling the shut-off time. Additionally, they prevent two flow fronts from meeting in the middle, significantly reducing cosmetic issues on injection molded parts .   Hot runner systems offer numerous benefits in injection molding, including faster production cycles. However, without the valve gate, the mol...

  In the past, it was difficult to find a 3D printing prototype service due to high costs and a limited number of companies providing it. But with the growing accessibility of additive manufacturing, service providers are now able to reduce their prices. The real challenge lies in determining which service provider truly has your best interests in mind. To make the process easier, look at the following factors when choosing a 3D printing partner:       What are their 3D printing capabilities?   Reputable prototyping specialists offer a wide range of tried-and-true additive manufacturing technologies like stereolithography ( SLA ), selective laser sintering ( SLS ), and fused deposition modeling ( FDM ). Moreover, they specialize in advanced and specialized 3D printing technologies like ProJet MJP and direct metal laser sintering ( DMLS ). Aim for a  3D printing prototype service  with all these solutions to avoid finding multiple companies...

  One common misconception about 3D printing is that it is limited to producing plastic parts. But actually, advancements such as DMLS (Direct Metal Laser Sintering) have made it possible to create high-quality metal prototypes using 3D printing technology. This makes metal 3D printing a compelling alternative to other metal fabrication methods like sheet metal and CNC machining.   Metal 3D printing, particularly DMLS, is an industrial rapid prototyping solution that works similarly to selective laser sintering (SLS). It builds parts by sintering powdered metals layer by layer, allowing for the creation of highly complex metal components that would be difficult or prohibitively expensive to produce using traditional methods.   DMLS 3D printing is a rapidly evolving technology with growing potential for use in both rapid prototyping and end-use manufacturing. It offers a range of benefits:       Achieve metal parts with complex geometries...
