Tapping Process: How to Achieve Perfect Tapped Hole? Tapping holes isn’t a process that can be easily completed. Before tapping holes on bronze casted parts, a technician should collect all pertinent measurements beforehand. Otherwise, a poorly tapped hole may lead to the wrong thread finish or size, which can then lead to a failure of…
Plating PC / ABS Process Flow To form good adhesion between the metal coating and the plastic base material, the most important step is to soak in an etching solution, which is usually a mixture of chromic acid and sulfuric acid. The electroplating process of electroplating PC/ABS is as follows: (1) Inspection of plastic parts,…
Common Ways To Improve Plating What? Dec 26, 2018 1. Component design and plating process If stress is applied, there is a certain stress in the plastic part, which will bring a lot of problems to the roughening of the plastic parts and the subsequent series of pretreatment processes. Therefore, plastic parts with higher stresses…
The Injection Molded Transparent Parts Are Not Transparent Enough. What Should I Do? Due to the high light transmittance of transparent plastics, the surface quality of plastic products must be strict, and there must be no markings, pores or whitening. Fog, black spots, discoloration, poor gloss and other defects, so the raw materials, equipment throughout…
The Injection Molded Transparent Parts Are Not Transparent Enough. What Should I Do? (2) Cleaning of the barrel, screw and its accessories In order to prevent contamination of raw materials and the presence of old materials or impurities in the recesses of screws and accessories, resins with poor thermal stability are present. Therefore, the screws…
