Effect of hot runner in plastic mold design Hot runner is indispensable in injection molding. For plastic processors, the key to benefit from Hot runner is to select the hot runner which is suitable for product forming and to master the correct use of hot runner. Hot Runner (HRS) also known as the water, that […]
The plastic mold is made up of two parts, the movable die and the fixed mold, which is installed on the moving template of the injection molding machine, and the fixed die is installed on the fixing formwork of the injection molding machine. During injection molding, the casting system and the mold cavity are formed […]
1, by the characteristics of the material itself caused by leakage hazards: (1), the thermal conductivity of the metal plate itself is large, when the external temperature changes greatly, due to changes in environmental temperature, due to temperature changes caused by shrinkage of the color plate at the interface to produce a greater displacement, and […]
The setting and adjustment of the process parameters in the die-casting production directly affects the quality of the product. A parameter may cause multiple defects in the product, and the same product of the same defect may be related to a number of parameters, requiring in the test die casting production to carefully analyze the […]
Plastic extruded plastics are thermoplastics – they melt upon heating and re-solidify upon cooling. Where does the heat of molten plastic come from? Feed preheat and cylinder / mold heater may work and are very important at start-up, however, the motor input energy – the motor to overcome the resistance of the viscous melt The […]
Vacuum casting is the process of using a ventilated mold. The molten metal flows into the mold by air pressure and then removes the air to form a vacuum. This casting method is mainly used for small parts with fine details or jewelry. Vacuum casting equipment, three kinds of sealed form, is based on everyone […]
Die casting refers to the molten alloy in high pressure, high speed conditions filled mold cavity, and under high pressure cooling molding casting method, casting process is the most widely used, the fastest growing metal hot forming process. Die casting as an advanced non-ferrous alloy precision parts forming technology, to adapt to the modern manufacturing […]
The working principle of the extruder is: the use of a specific shape of the screw, rotating in the heated barrel, the plastic sent from the hopper to squeeze forward, so that plastic uniform plastic (that is, melting), through the nose and different shapes Of the mold, so that the plastic extrusion into a continuous […]
The five systems of plastic mold are: pouring system, forming system, cooling system, exhaust system, ejection system. First, the plastic mold of the pouring system The pouring system consists of a runner, a gate, which is a system that injects molten material into the injection molding machine between the nozzle of the injection molding machine […]
Plastic mold is a combination of tools, in many ways need to use this mold, so the purchase of this mold is also needed, then when buying this mold is the need to pay attention to the relevant matters in order to be able to buy better Mold. Do not just pay attention to the […]
