The molding mold according to different materials, mold can be divided into metal molds, plastic molds, as well as their special mold. Mould is divided into: including stamping die (such as stamping dies, bending dies, drawing die, turning hole mold, mold shrinkage, undulating mold, bulging mold, plastic mold, etc.), die (such as forging dies, Upsetting die, etc.), extrusion dies, extrusion dies, die casting mold, forging mold. Qingzhou Han Heavy Industry Co., welcome new and old customers to buy. The purpose of annealing cement pipe machine manufacturers, to reduce the hardness of steel, easy machining, but also for the subsequent heat treatment for tissue preparation. Carbon tool steel annealing organization chart by GB1298 first level rating assessment. Carbide inhomogeneity ledeburite Cr12 type, tissue contains large amounts of eutectic carbide, carbide inhomogeneity have a very significant impact on performance, so its distribution carbide must have strictly controlled. In short, because of mold manufacturing plant and production workshop more complicated objects, and how much they are single, small quantities, so as to mold the development and management of production quotas to bring some degree of difficulty, coupled with the plant and plant production, equipment, technical quality but not the same cement pipe machine, so when developing quotas must Weifang cement pipe factory and workshop based on the actual situation, identify the appropriate method to develop both advanced and reasonable fixed working hours, aim to improve labor productivity. Hot runner mold: This mold structure and fine nozzle much the same, the biggest difference is that in one or more of the flow channel has a constant temperature heat pump manifold plate and mouth, no cold feed stripping Shandong cement pipe machine, runner and gate directly on the product, so no need stripping runner, this system is also known as non-outlet system, saving raw materials for raw materials more expensive, higher product requirements, the design and processing difficulties, high tooling costs . Hot runner systems, also known as hot runner system, mainly by thermal gate sets, hot runner plate, temperature control electrical box. The most common hot runner systems have a single point and multi-point hot runner runner two kinds of forms. Single-point thermal gate is directly injected into the molten plastic cavity hot runner with a single set, it applies to a single gate single cavity plastic mold; multi-point thermal gate hot runner through the plate to melt into each branch Heat and sprue bush and then into the cavity, which applies to single-chamber or multi-cavity mold feeding cement pipe machine retail |.
