Plastic mold production and processing common problem and cause reason and solution

What different plastic mold and molding grinding have
plastic mould is awarded in forming plastic with image and specifications of the components. Grinding tool structure though because the types and characteristics, the appearance of the plastic products and plastic structure and type of injection machine and so on is different and will be various, but the infrastructure is the same. Plastic moulds for thermosetting plastic injection mould, according to the forming characteristics of difference between two kinds of thermosetting plastic injection mold; In accordance with the forming process difference for mold, injection mold, casting mold, hot forming mold, pressing die, Pressure mould) , an injection mould, etc. , in which pressure clamping with flash method and can be divided into overflow type, half overflow type, not overflow type three, an injection mould for casting system software can be divided into cold runner mold, the mold hot runner system two; According to handling methods can be divided into a portable, mobile two kinds. Grinding classification is based on the different of the process to carry out the difference. Plastic mould is to put the molten plastic with a certain rate, a certain work pressure injection into Sue the abrasive die, after being plastic cooling, open abrasive took shape of die casting. Pressure molding grinding tool known as membrane _ will immediately plastic raw materials in open abrasive die, will be closed grinding tool, and plastic work in heat and pressure into liquidity situation and fill under the effect of concave die, then via the chemical crosslinking or physics refrigeration products YingDeHua setting. Molding grinding tool is the plastic heating with heating of abrasive suppress forming and then out of the mould, the shape of goods, into the cold water to carry out the setting refrigeration. Forming is compression forming an key technical process, the production and processing in industrial production, industrial production has widespread use in production and processing, in the daily life of the people give full play to the key effect. Generally is the powder, granular, granule, block, or even to make a similar appearance and product of billet, into the cavity of the heating of the abrasive, then closing pressurized and make its forming and dry solid or vulcanized rubber, then through the mold product ( See the figure) , which is very applicable thermosetting plastics ( See the thermosetting resin) The forming of production and processing. Defect is the production time is long, low efficiency, poor precision of product specifications.
plastic mold production and processing common problems
as a plastic mold production and processing of production process, in the making or how many there will be a point after the status of the poor. Encounter this kind of situation people injection mold manufacturers how to solve? Below is guys detail in plastic mold production and processing of common problems and the caused reason and solution. An albino plastic products, plastic mold production and processing mold production and processing of bleaching products are: 1, too much stress at work. 2, the mold. Encounter this kind of situation, the overall solution, in plastic mold design should pay attention to when the inclination of the mold wants enough, making plastic moulds, plastic injection mold die to maintain smooth, be sure to parallel processing should be immediately reduce shoot out work pressure. Second, potholes in plastic injection mold production and processing of pits are caused by the plastic mold production and processing: 1, plastic mold cooling is not adequate, cooling time is not enough but will cause serious deformation. 2, the essence of plastic moulds working pressure is not enough also can appear this kind of situation. 3, is not the same as the product of each part of its thickness. Encounter this kind of situation, people as a whole have relative solution: reduce the cylinder temperature and grinding tool temperature, in the cause of pit area forced cooling, pit area of the fill side of celebrity, regulatory design products the difference of its thickness.
