Mold temperature affects several aspects of surface quality, liquidity, shrinkage, molding cycle and deformation. Mold temperature is too high or lack of different materials will have different impacts . Thermoplastics , the mold temperature is usually a little higher will improve the surface quality and liquidity, but will extend the cooling time and MASTER plastic pallet mould cycles. Little lower mold temperature will reduce shrinkage in the mold , but will increase after stripping shrinkage of injection molded parts . And thermosetting plastics , the high point of the mold temperature will typically reduce the cycle time , and the time determined by the time required for cooling parts . In addition, plastic machining, mold temperature a little higher will reduce the plasticizing time, reduce cycle times .

MASTER injection mould design of die maintenance directly affects the surface quality of products

Attention should be paid to the surface of die maintenance, it directly affects the surface quality of products, the focus is to prevent corrosion, therefore, choose a suitable, high-quality,MASTER china plastic injection molding professional anti rust oil is particularly important. When the mold to complete the production task, should adopt different methods according to different carefully remove residual injection molding, available copper rod, copper wire and professional mold cleaning agent to remove residual injection mold and other sediments, and then air dried. Disable MASTER injection molding supplies wire, steel bars and other hard objects to clean, so as not to scratch the surface. If the rust corrosion caused by point injection, to use the machine for grinding and polishing, and a professional anti rust oil spray, the mould is then placed in dry, cool, no dust at the store.

MASTER injection mold maker of temperature control system to control the mold temperature

Preparation conditions of temperature control system control mold temperature, mold temperature machine, the MASTER plastic container molding heat transfer fluid is composed of three parts. In order to ensure that heat can be added to the mold or moved, each part of the system must meet the following conditions: the first is in the mold, cooling channel surface area must be large enough, the ability to channel diameter to match the pump (pump pressure). The temperature distribution in the cavity on the deformation and internal pressure have a great impact. A reasonable set of cooling channel can reduce the internal pressure, so as to improve the quality of injection MASTER plastic mold manufacturerparts. It also can shorten the cycle time, reduce product cost. The second is the mold temperature machine must be able to keep constant temperature heat conducting fluid in the range of 1 ℃ -3 ℃ within, depending on the product quality requirements set. Third is a heat transfer fluid must have good heat conduction ability, the most important is, it must be able to import or export a large amount of heat in theshortest amount of time. From the thermodynamic point of view, the water is more obvious than that of oil well.

The working MASTER injection mold maker principle of injection mold

The working principle of mold temperature machine consists of a water tank, heating and cooling system, power transmission system, the liquid level control system and a temperature sensor, injection port devices. Usually, power transmission system in the pump so that the thermal fluid from the tank is equipped with a built-in heater and MASTER injection mold maker cooler to die, then die from the back to the water tank; temperature sensor to measure the temperature of hydrothermal fluids and transmit data to the control part of the controller; the controller adjusts the hydrothermal temperature, thereby indirectly control the mould temperature. MASTER molds for plasterIf the mold temperature machine in production, mold temperature exceeds the set point of the controller, the controller will open the electromagnetic valve is communicated with a water inlet pipe, until the heat fluid temperature, the mold temperature to the set point. If the mold temperature is lower than the set value, the controller will turn on the heater.

MASTERplastic injection mold makers mould is engaged in plaster painted friends or indispensable tool

Plaster mould is engaged in plaster painted friends or indispensable tool, quality made plaster friends are clearly made out of plaster, texture clear and smooth plaster mold is inseparable. Now the plast. Now the plaster mold material on the market there are PVC, resin, MASTER injection molding supplies rubber, vulcanized rubber and so on, then how the plaster mold what kind of material is good, judge the mold quality is qualified or not is very simple is whether the mold stripping, the mold is soft hard moderate. PVC, resin material market exists but the plaster mold is the two materials made of no, because the plaster mold is roasted in high temperature furnace, the two materials is baked not die at high temperature. So that is a resin, PVC material manufacturers must be lied to. Die really good material is pure rubber MASTER plastic injection mould material, mold the material for strong, soft hard moderate, easy demoulding. Die market price 12 yuan, 10 yuan is made of vulcanized rubber. Vulcanized rubber cost than pure rubber material to do 2 to 3 times. But the plaster mold made difficult to release, not smooth, many buy back after customers began to regret not greedy little cheaper. Tell our friends what the plaster mold material is good, want to buy time to rational, a penny a cargo, not greedy small and scattered.
