Mold Overall Toughening Treatment The die steel is widely used. The conventional heat treatment process is quenched at 1050 °C ~ 1100 °C, tempered at 550 °C ~ 620 °C, and the hardness is generally 45 HRC ~ 50 HRC. The early fracture phenomenon often occurs in use, and the die life is often low.…
DetailsMold Surface Strengthening Treatment In recent years, with the development of industry, the requirements for product quality have become increasingly strict, and the requirements for molds have become higher and higher. In particular, precision die-casting molds require a high degree of mechanical properties, and require a small amount of deformation, which is basically no longer…
DetailsWhat Is The Middle Wire Cutting Technology? The middle wire cutting process is a processing method that utilizes the thermal effect of the instantaneous discharge energy to melt and evaporate the workpiece material to meet the dimensional requirements. Since the wire-cut working fluid mostly uses a dielectric liquid, it is accompanied by a certain electrolysis…
DetailsWhat Are The Square Tube Forming Methods? The way in which the tube is formed is called bending, and the way in which the square tube is formed is called bending. There are two basic methods of bending forming: solid bending and empty bending. The solid bend, as the name implies, is the compaction of…
DetailsWorking Conditions Of Die Casting Mold The die-casting mold is the basic tool for the completion of the pressure casting production. The high-pressure 1000°C molten metal is die-cast at a high pressure of 150 MPa to 500 MPa, and the processed objects include lead, zinc, aluminum, magnesium, copper and other alloys. Due to the different…
DetailsDie Casting Mold Performance Requirements Pressure casting can cast parts with complex shapes, high precision, small surface roughness and good mechanical properties. Therefore, the die casting mold should have the following performance requirements: (1) Large high temperature strength and toughness The die-casting mold is subjected to high temperature, high pressure and thermal stress when molten…
DetailsThermal Expansion Technology To Improve Mold Life 1. Carburizing Different materials are generally treated by different heat treatment methods. The plastic molds of the low-carbon steel and low-carbon alloy steels are generally subjected to a carburizing treatment method, which has a fast percolation speed, a deep layer, and a layer. The composition gradient and hardness…
DetailsFrequently Asked Questions In Mold Design 1. The role of the secondary welding chamber Extrusion molds play a vital role in the extrusion of aluminum profiles, directly affecting the quality of extruded products. However, in actual production, the design of the extrusion die relies more on the experience of the designer. The quality of the…
DetailsApplication Of Hot Runner Technology For Injection Molds 1. Differences in mold structure In the molding of oversized plastic products, only the hot runner can be used to balance the plastic flow. For example, in the production of automotive interior linings, appliance housings and other components, more than the need to simultaneously enter the glue…
DetailsSix Key Points In The Design Of Aluminum Extrusion Die 1. Size analysis of aluminum extrusions The size and deviation of the extrusion are determined by the mold, extrusion equipment and other relevant process factors. Among them, the influence of mold size change is great, and the reasons for the change of mold size are…
