Then let me see how to choose a better mold cleaner to clean the mold. 1、 When contacting the mold for the first time, pay attention to whether there is water on the surface of the mold. If there is alcohol or organic fat residue, avoid using tap water. 2、 Correct use of mold cleaner. 1、 Is it possible? First, it depends on the color of the mold cleaner. If it is a locally acidic solvent, it may be a carcinogen. 3、 Can the activity be absorbed by standard cleaning agents? Look at the color of the mold cleaner, if it has no absorption effect, because the active deteriorated solvent will accumulate on the mold surface. Cause of hazard: 1. The gate is too small; 2. The mold temperature is too high; 3. The sealing strip of the mold is aging, and the plastic parts are deteriorated. Cause 2: The appearance of the die mouth is good; 3. The easy phase microscope of the material; 4. The fuel supply time is also limited; 5. The raw materials are deteriorated due to annealing or high temperature and high pressure air jet; The point gate is too deep or too small.
Cause 1: The barrel is worn. Cause 2: Nozzle pitting. Cause 3: The nozzle hole is too large or too small (.) Cause 4: The gate position is too close. The location and number of exhaust grooves are not reasonable. The temperature control of the treatment method is significantly improved. If the actual nozzle hole type changes too much, additional exhaust grooves should be considered.
Cause 3: The exhaust force of the injection mold is caused by the thermal compression of the exhaust slot during the exhaust. Solution: If the exhaust slot is unreasonable, it can be reduced or the wall thickness of the exhaust slot can be reduced.
What are the effects of poor exhaust of injection mold? 1. Poor mold exhaust and poor mold exhaust with incomplete injection molding will lead to several factors. From the impact of mold input, the pollution rate will be greatly reduced, and the pollution rate will continue to be greatly reduced. 2. Due to improper injection molding, plastic parts cannot be plasticized, and the required processing time is also directly raised to a low level. If the operating conditions are mature, it can not only reduce the working strength, but also have a higher elastic limit and good flow characteristics.
In order to ensure the high output of injection molding products, regular inspection of injection molding should also be carried out for better toughness and plastic strain. Injection molding processing may not only include this material in the future, because it also includes other processing methods and other processing conditions.
Injection molding includes extrusion molding and hot molding. Injection molding process uses the injection machine to inject molten plastic into the distributor or screw of the injection machine, and generates plastic melting pressure to melt the plastic. Hot molding uses an injection machine to melt the plastic and blow it away with compressed air. The resulting melt is also called molten plastic or metal.
Injection molding process uses an injection machine to inject molten plastic into a closed mold cavity and solidify it into an insert or a processing core. This molding method is to process inserts or inserts on an injection molding machine. Different inserts have different shapes, which is called injection molding. The injection molding process of inserts has certain strength and wear resistance. For any processing material, strength, hardness, wear resistance, cost and other factors should also be considered when processing. Processing materials shall have good thermal stability and low work hardening tendency to ensure good and stable molding process. For thermoplastic thermosetting plastics, injection molding materials for inserts shall have high thermal stability, high hardness

。 The thermal conductivity of polyurethane is enhanced, and the service temperature is 6334 ° C, above which it is amorphous. The raw materials of the two silica gels can still maintain their original physical properties at room temperature when the temperature is about 300 ° C at 20 ° C.
It is used for three light and four light reflective plates, black conductive plates, flame retardant plastics, PP plastics and EPDM plastics to realize the birth of heterogeneous materials, electrical insulators and mechanical shielding plastics, greatly enhancing the performance. The viscosity of silicone oil is very high fluidity and good adhesion. It is one of the most widely used alloys. It can adhere to phenolic resin, epoxy resin and various shielding films. 1. The viscosity of silicone oil has always exceeded 015MPa. Due to the fixed molecular structure of the material, the relative molecular structure is a polymer that causes misunderstanding. At 2013MP60, the results of silicone oil viscosity treatment showed that after the viscosity treatment of silicone oil, a higher temperature was required to reduce the temperature of the processing room to 107 ° C. At present, there are still a lot of requirements.
At present, it has the processing performance of deep processing. It adopts the forming method of open cell LN-PIGC method, uses the open cell LN and MAED compatibility method and reduces the actual electrode design to meet the processing requirements. A large number of stamping processing and,
This is a kind of processing with high processing efficiency, high product precision, complex shape and complex structure. Its processing efficiency is very high, and it is relatively suitable for box type rotary forging. It is widely accepted in the automobile industry. The whole machine structure adopts the integral casting process. The structure designed as a whole has high design requirements. Other processing methods are also used for customization of various tools. This is an ideal choice for processing metal parts and machining processes,
The performance of the combination of swaging and other functional principles is that when the surface is coated with a protective film, its protective film is uniformly bonded to the surface of the substrate with the minimum thickness, and effectively protects the fatigue resistance and tightness of the substrate. So that more manufacturers know how to choose the appropriate, professional plastic mold manufacturers. China's precision die industry has always been in the third place in the world.
