Die Cut Blanks Port Design The function of the blanking opening is to hold the parison and seal it during the blow molding process. The most important thing to note when designing the blank is the amount of blank left in the two molds. If the blank of the blank is designed to be small,…
Characteristics Of Surfacing Welding Repair Technology Compared with general TIG welding, laser surfacing welding has the characteristics of small welding input heat, no need for preheating and post-weld treatment, making it possible to perform fine precision surfacing welding in the past. Since TIG welding is a high-heat melting workpiece and a surfacing material on the…
Rapid Prototyping Is Also Known As Rapid Prototyping Manufacturing Rapid prototyping technology, also known as Rapid Prototyping Manufacturing (RPM) technology, was developed in the late 1980s and is a high-tech manufacturing technology based on material stacking. It is considered to be a major achievement in the manufacturing field in the past 20 years. It integrates…
Rapid Prototyping Technology For Injection Molding Metal Molds In this metal light molding method, a single process which is impossible in the original mold processing can be realized, and therefore, it is possible to expect a short lead time and a low-cost metal mold production. In the processing method, the internal structure can be freely…
Laser Forming Technology And Laser Bending Forming Technology The laser impact forming technology refers to a technique in which a coating layer of a sheet metal workpiece is irradiated with a laser, and a shock wave is generated by thermal evaporation of the covering layer to achieve plastic deformation of the workpiece. Before the laser…
Forging Forming Process Forging shape is one of the two major components of forging (forging and stamping) by using a forging machine to apply pressure to a metal blank to plastically deform it to obtain a forging having certain mechanical properties, a certain shape and size. Forging can eliminate defects such as as-cast looseness caused…
What Is The Basic Process Of Plastic Thermoforming? The basic process of thermoforming is: sheet clamping, heating, forming, cooling and demoulding. Among them, molding is the most important and complicated. Most of the thermoforming is carried out on a molding machine, which varies greatly depending on the thermoforming method. It is not necessary to complete…
Heat Treatable And Non-Heat-Type Material Classification Generally, which mold material is selected is determined by the composition of the molding resin and the number of die casting. That is to say, the amount of glass fiber in the resin (hereinafter referred to as GF) and the amount of die casting are important factors in selecting…
Heat Treatment Conditions And Mold Quality The mold subjected to heat treatment is deformed during quenching and tempering. Therefore, it should be cooled as quickly as possible in order to meet the heat treatment quality requirements. This is in contradiction with the need to resist the deformation as slowly as possible. It is necessary to…
How To Properly Maintain Rubber Molds Everything has a certain life span. In order to extend the service life, we need to know how to maintain it properly. The following is about the correct maintenance of rubber molds. First, the regular maintenance of the mold wear curve is present in each mold. Mold repair is…
