Mold processing is a very complex and arduous task.

  Mold processing is a very complicated and arduous task, and we need to understand the full range of information about the target plastic injection parts, so we should make full preparations before the injection mold processing. It is also necessary to fully understand the use of the plastic parts, the role of each part of the plastic parts, clear molding shrinkage, transparency, dimensional tolerance, surface roughness and allowable deformation range. Casting system is an important part of mold processing. Casting system is to fill the melt into the cavity of injection mold uniformly and quickly to form regular plastic parts.

  The mould processing in Dalian consists of main stream, diversion channel, gate and cold material hole. Each component has its own role, jointly complete the whole process of pouring, the role of each component is described below. Main stream: a passage that connects the nozzle to the mold to melt the material is called the main stream. It can effectively transfer pressure, prevent the melt solidified too fast, and distribute pressure equally into other channels. Shunting Road: the flow channel connected to the various slots after separating from the main channel. In order to balance the pressure distribution between the runners, the distributor is generally symmetrical distribution, using the natural balance layout to transport the melt to the gate, can make the filling process of the material uniform, to prevent the occurrence of substandard products.

  Gate: the cavity is filled with material, and the gate is cooled quickly to prevent the molten material from returning. The gate is a small part of the whole runner system, but it has great influence on the molding of plastic parts. Gate design directly affects the quality of plastic parts, according to the shape and structure of plastic parts to design the appropriate gate. Cold material well. Storage of cold materials. Filter out the cooled melt, and make good melt can smoothly fill the cavity of a link to prevent unqualified cold material into the cavity on the plastic parts have a negative impact or plug gate, so as to avoid the appearance of the product is not good, affecting the quality of plastic parts. According to the appearance structure and product performance of plastic parts, the gating system design should be adjusted accordingly to achieve high quality and qualified injection mold.
