Factors to Consider When Selecting Plastic Extrusion Molds

Selecting the correct plastic extrusion molds can improve the quality and efficiency of the final products. Due to the huge number of choices available, understanding the fundamental principles at the basis of such a selection would be greatly beneficial. Here are some of the key criteria that will help when choosing plastic extrusion molds which companies like POLYWELL, that fabricate plastics, understand these parameters. 

1. Material Compatibility

The first consideration, without a doubt, concerns the compatibility of the material that will be molded versus the plastic that is going to be extruded. As it is common knowledge, there are plastics, which can be classified as having differing melting and flow characteristics, among others, which can certainly pose interference to the effective operation of the mold. In this case, however, it is essential to choose a mold material that can withstand the processing temperature as well as the chemical composition of the plastic material used. 

2. Mold Design and Geometry 

The final product also takes into account the design of the mold which aids in the design of the extruder shape. Even more important are the technical parameters of wall thickness, the characteristic complexity of the part geometry, and the cooling channels.

POLYWELL considers it also important that the geometry of the molded part ensures a uniform flow of the material. This way, such geometry will in most cases assist in minimizing the defects in the molding process.

3. Production Volume

There is another significant parameter that relates to the volumes of production that are expected. In cases of high production volumes it is worth using mold with more cavity number and high precision ambition. Whereas for smaller production volumes, some of the manufacturers could go for lesser mold cavity number. POLYWELL has a variety of molds that cater for both low and high volume productions ensuring that various types of manufacturing processes are accommodated.

4. Lead time and Cost

Mold lead time is such other factor that in some instances can guide what plastic extrusion mold to settle for. Custom molds may take too long to produce and cost a lot of money too. POLYWELL has reasonable prices for production and delivery time so that even when quality standards are high, the clients will not be late for their work.

5. Maintenance and Support 

Also, never forget to contemplate the maintenance of the molds and the amount of support that the supplier will provide. Maintenance can be relied upon to a considerable extent so as to enhance the quality and the quantity of production molds. POLYWELL takes pride in rendering good customer care services and support regarding the issues related to the mold during its operations.

In addition, mold design, material of the used injection or extrusion die, the amount of production and other factors such as the manufacturer’s capabilities, processes and equipment, maintenance and time frame for the mold’s design, production and testing are among the key determinants for the choice of suitable plastic extrusion molding equipment for a manufacturer. POLYWELL is ready to help customers in these aspects by supplying appropriate molds which are designed and manufactured to ensure good production performance. The cooperation with POLYWELL enables enterprises to undergo well-organized and effectively implemented plastic extrusion processes leading to high-quality end-products.
