Why Manual Smoothing Polishing is Required for Plastic Injection Molds produce plastic parts ?/??

 

Injection molded products are the result of a design concept being realized through mold manufacturing and injection molding. The mold plays a crucial role in this process. Injection mold manufacturing involves many steps. Today, I'll discuss the Smoothing Polishing process for injection molds. After mold processing, CNC tool marks or spark patterns from EDM remain on the mold surface. This is when the mold needs to be polished. Smoothing polishing improves the finish of the molded product. Mirror-finishing EDM machines can also perform this task. However, most manufacturers perform manual Smoothing Polishing. This seemingly simple, repetitive process is actually quite complex. Today, I'll explain why manual Smoothing Polishing is required for injection molds.

 

Smoothing polishing serves two purposes: 1. To improve the surface finish of the mold, resulting in a more attractive and beautiful product.

 

2. To ensure better mold release, improve calibration rates, and prevent product sticking. Poor mold surface roughness is very prone to sticking. Proper Smoothing Polishing is crucial for producing high-quality, beautiful products and improving production efficiency.

 

Using a mirror-finishing EDM machine to process parts can achieve a mirror-like finish. Both mirror-finishing and manual polishing can improve the finish of molds. The difference is that mirror-finishing EDM is primarily used for precision machining of complex mold cavity surfaces, shortening production cycles. However, the processing cost is higher than with standard EDM. Manual polishing, on the other hand, is used to achieve parts that cannot be processed using mirror-finishing EDM. While manual polishing produces a high finish, it also has the disadvantage of a longer production cycle.

Manual polishing requires extremely strict requirements during the initial processing phase. Each polishing technician must perform meticulously and carefully, and every process step must be inspected. This improves the quality of polished mold parts, which is one of the reasons why Shibang Injection Mold Factory has been established in the industry for many years and has been recognized by many customers.
