Basic Work Cognition Of Injection Molding Machine 1.Melt temperature The nozzle can be measured or measured by air jet. When using the latter for measurements, care must be taken to ensure that hot melt plastics are cleaned without accidents, as hot melt plastics can burn the skin and even corrode the skin. In the injection…
How To Disassemble The Screw Nozzle Of The Injection Molding Machine? The plasticizing device is generally provided with an integral rotating mechanism. When loading and unloading the screw nozzle, screw and barrel of the injection molding machine, firstly, the injection molding positioning screw should be loosened to deflect it from the original position by a…
Repair And Maintenance Of Screw Nozzle Of Injection Molding Machine If there is a one-side contact or poor contact in the contact part between the nozzle and the mold positioning sleeve, the front end spherical portion R will be deformed to form a groove in which the melt escapes, causing the nozzle to overflow, and…
Automatic Insert Molding System Design Choices Considerations 1. Metal insert molding is prone to uneven molding shrinkage, and the limit test of shape and dimensional accuracy of important parts should be done in advance. 2. The metal insert is easily deformed and displaced during the injection process, and the design of the mold and the…
How To Analyze The Damage Of The Stamping Die? 1.Check whether the manufacturing material of the stamping die is suitable, and whether the corresponding heat treatment process is reasonable. The heat treatment process of the stamping die material usually has a great influence on it. If the quenching temperature of the stamping die is too…
Insert Injection Molding Technology Features 1. The combination of the moldability and flexibility of the resin and the rigidity, strength and heat resistance of the metal complements the complex and intensive metal-plastic integrated product. 2. In particular, the combination of the insulating properties of the resin and the electrical conductivity of the metal can be…
Precision Injection Molding And General Injection Molding 1. The characteristics of precision injection molding are that the dimensions of injection molded parts require high precision and small tolerances. The conditions that must be met to achieve precision injection molding are: (1) The material of the mold is good, the rigidity is sufficient, the dimensional accuracy…
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…
Matters 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…
Highlights 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…
