Highlights Of High Gloss Mold Design 1. High-gloss mold requirements for product structure Gaoguang Mould has strict requirements on product structure. It is well known that the brighter the product is, the more sensitive it is to the refraction of light, and the slightly flawed surface will soon be discovered. Therefore, how to solve the…
Analysis Of The Causes Of Mold Burst 1. The mold material is not easy to be broken during subsequent processing. 2. Heat treatment: improper quenching and tempering process produces deformation. 3. The mold is not flat enough to produce flexural deformation. 4. Design process: the mold strength is not enough, the knife edge spacing is…
How To Prevent Mold Cracking 1.Stamping equipment The accuracy of stamping equipment (such as presses) and the impact of rigid on die life are extremely important. The precision of the stamping equipment is high, the rigidity is good, and the die life is greatly improved. Especially for small gap or gapless die, carbide die and…
Three Characteristics Of Mold Processing 1. High precision, the mold not only has high processing precision, but also has good processing quality. In general, the tolerance range should be controlled on the order of microns. Only high-precision molds can guarantee the product to achieve a certain degree of precision, and to ensure the product’s pass…
Specific Measures To Improve The Life Of Die-Casting Molds The cutting stress generated during the mold processing, the stress of the spark discharge metamorphic layer, and the thermal fatigue stress generated during the die casting can be alleviated or eliminated by annealing. The mold should be periodically annealed to eliminate stress: the first stress relief…
Five Major Defects In Mold Casting 1.Casting shrinkage hole The main reason is that the alloy solidification shrinkage produces casting shrinkage cavities and the alloy absorbs a large amount of oxygen, nitrogen, etc. in the air. When the alloy solidifies, gas is released to cause casting shrinkage. The solution (1) Place the gold ball. (2)…
Matters Needing Attention When Using Die-Casting Mold Materials The mold material should have good machinability and easy finishing; it has high heat treatment hardenability, which makes the internal and surface microstructure and properties after quenching uniform, and the dimensional deformation is small; durable high temperature plasticity and thermal fatigue resistance, The mold will not be…
Temper Brittleness Of Steel 1. Temper brittleness refers to the phenomenon that the toughness of the quenched steel decreases after tempering. When the quenched steel is tempered, the hardness decreases and the toughness increases as the tempering temperature increases. However, in the relationship between tempering temperature and impact toughness of many steels, two valleys appear,…
Mold Meets Process Performance Requirements Mold manufacturing generally involves several processes such as forging, cutting, and heat treatment. In order to ensure the quality of the mold and reduce the production cost, the material should have good forgeability, machinability, hardenability, hardenability and grindability; it should also have small oxidation, decarburization sensitivity and quenching. Deformation cracking…
How Is The Life Of The Mold And The Structure Related? In the actual application, the factory often determines that the mold has failed when the cost of re-maintenance reaches about 1/3-1/2 of the re-production cost, and then the repair is often not worth the loss. The failure of the mold is divided into abnormal…
