TH4607U - Manufacturing process of brushes for applying PVC pipe adhesive. - Google Patents

Abstract

The manufacturing process of a PVC pipe adhesive brush involves using bristles made of nylon fibers and a handle made of hollow plastic. The bristles and handle are joined together using heat and pressure from both sides, deforming the bristles and handle and resulting in a strong, fused bond.

1. The manufacturing process of the PVC pipe adhesive brush consists of bristles made from nylon fibers (1) cut into sections, each bristle length 4 centimeters, and a handle made of a cylindrical plastic with a hollow hole in the middle (2), 10 centimeters long, with a hollow hole diameter of 0.5 centimeters and an edge thickness of 1 millimeter. The specific characteristics of the manufacturing process are as follows: First step: Cut the bristles made from nylon fibers into sections, each bristle length 4 centimeters, and the cylindrical plastic handle with a hollow hole in the middle, 10 centimeters long, with a hollow hole diameter of 0.5 centimeters and an edge thickness of 1 millimeter. Second step: Assemble the nylon fiber bristles onto the plastic handle by inserting them into the hollow hole of the handle 2 centimeters in. Then, use a steel mold heated to 95 degrees Celsius to press down on the ends of the handle, both top and bottom, simultaneously for 10 seconds. The heat and pressure will soften the ends of the handle and the nylon fiber bristles and flatten them. This process will cause the nylon fiber bristles inside to be pressed firmly onto the ends of the plastic handle.
