Multi-Color, Multi-Component Applications For Vertical Injection Molding Machines The application of vertical injection molding machine in multi-color injection molding, the combination of vertical machine and horizontal machine forms a multi-station two-color or even multi-color molding process. The turret type two-color machine is also called core rotary injection. That is, there is a shaft that can…
DetailsMatters Needing Attention When Designing Die-Casting Molds Reasonable design of castings, castings should have a uniform wall thickness, not too thin, too thick, generally about 2 to 3.5 mm thick, corners or slopes should be rounded or sloped to reduce stress concentration, and the rib structure can be used to eliminate castings. The hot section…
DetailsHighlights Of High-Gloss Molds The high-gloss mold controls the mold temperature through the mold temperature machine, and the hot runner, solenoid valve and time relay control the time-division glue to produce high-end products with defects such as bright surface, no shrinkage and no weld mark. High-gloss molds generally have the following characteristics: 1. The mold…
DetailsHighlights 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…
DetailsAnalysis 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…
DetailsHow 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…
DetailsThree 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…
DetailsSpecific 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…
DetailsFive 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)…
DetailsMatters 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…
