Thermoplastic substrate forming machine

This creation relates to a thermoplastic substrate forming machine, and more particularly to a molding machine for forming thermoplastic materials.

In recent years, the more diversified materials are used, among which alloy materials or ceramic materials are often used in different fields due to their hardness-enhancing properties. This type of material is formed by adding raw materials to plastics and mixing them into a viscous shape. After the plastic is volatilized and solidified by a sintering process, an alloy material or a ceramic material of a specific shape is formed.

However, before the sintering process, the substrate is formed by blending the raw materials into a viscous shape, and then forming a substrate of a specific shape by a cutting process to perform a sintering process, but the raw material is subjected to a cutting process. After that, the peripheral edge of the substrate is liable to generate internal stress due to the force of the cutting blade, so that the peripheral edge is lifted during the sintering process, and a defective product is formed, and the elimination rate is relatively high.

Furthermore, the current molding method requires a cutting process to obtain the substrate. Therefore, in addition to the substrate obtained by the cutting blade, the substrate must be removed from the scrap before the sintering process can be performed. Therefore, the entire production process is cumbersome, the production capacity is also affected, and the waste is generated due to the waste generated during the molding process. Therefore, in the case of low production capacity and high cost, the market competitiveness is lowered.

The scraper portion of the end is flattened at the top of the raw material in the molding space to form a flat substrate, thereby directly forming a substrate of a specific shape by the molding machine, which not only reduces the defect rate, but also generates waste, and further, automatic molding In this way, the process can be simplified and mass-produced, so that the purpose of increasing production capacity and reducing costs can be achieved.
