What Do YOU Know About Mold Steel Quality?

-

Many industries place strict requirements on the acceptable level of surface defects and imperfections that may appear on a plastic molded part. Such conditions often apply to critical components for the medical and pharmaceutical industries as well as for the manufacturers of lenses and other optical devices. However, for aesthetic reasons, many other consumer goods have similar restrictions. After all, any defect that appears on the surface of the mold steel is likely to be replicated onto the molded part. Problems associated with the texturing or polishability of a mold cavity can often be traced back to the mold steelmaking process. The material properties that have shown the greatest influence on obtaining a good surface finish are the microcleanliness level, the severity of chemical segregation and the appearance of primary carbides. The mold steel's chemical composition along with the manufacturing techniques used during its production, will determine its ability to p...

Computer controls and automation can greatly enhance certain manufacturing capabilities. Under computer numerical control (CNC) parameters, tasks that were formerly considered impractical can be accomplished quickly and with a high degree of precision. CNC programming can be designed to match multiple production needs, allowing an automated machine to specialize in a range of fabrication projects. Despite the expanding role of computer controls, CNC-based production is still dependent on its machinery. This makes selecting the appropriate components and machine tools a priority regardless of the level of automation in a system. In the case of drilling machines, such as mills and routers, the type of drill bit used can be a significant influence on the final product. CNC programming can control the feed and depth rate in a drilling cycle, as well as the repetition of specific drilling operations, but choosing a well-suited drill bit remains the manufacturer’s decision. Twist and...

Everything You Need To Know About Injection Molding

图片
What is Injection Molding: Injection Molding is a manufacturing process for producing parts in large volume. It is most typically used in mass-production processes where the same part is being created thousands or even millions of times in succession. Why Use Injection Molding: The principal advantage of injection molding is the ability to scale production en masse. Once the initial costs have been paid the price per unit during injection molded manufacturing is extremely low. The price also tends to drop drastically as more parts are produced. Other advantages include the following: Injection Molding produces low scrap rates relative to traditional manufacturing processes like CNC machining which cut away substantial percentages of an original plastic block or sheet. This however can be a negative relative to additive manufacturing processes like 3D printing that have even lower scrap rates. Note: waste plastic from injection molding manufacturing typically comes consistent...
