It is possible to mechanically add a knockout and create a molded part with an undercut!
In convex molding, the molded product shrinks as it cools, tightening against the mold, which makes demolding difficult. Therefore, a draft angle of about 2 degrees or more is generally applied. If the side walls of the convex mold are finished smoothly, demolding becomes easier, especially for highly fluid materials like polyethylene and polypropylene, where it is essential. By slowing down the descent speed of the table and blowing out demolding air while lowering, and by creating air holes for demolding air at the top of the mold, demolding can be done easily without deforming the molded product. *For detailed information, please refer to the related links.

Company information
There are various molding methods for plastic molding processing, but our company's vacuum forming (vacuum molding) has lower mold costs compared to other molding methods and allows for small lots of a wide variety of products. This enables us to mass-produce plastic containers at a low cost within a quasi-cleanroom factory. Additionally, due to its high versatility, plastic containers such as conductive trays, frozen food containers, cosmetic trays, blister packs, barrier trays, clear cases, and biodegradable plastics are used in various fields.
