The purpose of mold design and manufacturing is for the mass production of injection parts with high efficiency and high quality, to produce high-quality plastic parts , the first mold is good, a good set of plastic molds is not just a good look, want to do a set of high-quality, high level, high precision plastic molds, from the following aspects. 1. The smoothness of the injection mold surface The polishing of the mold surface is very important, which is one of the most important links to determine the success or failure of mold manufacturing. The surface of the mold is not smooth enough, its surface is uneven, and the surface of the plastic parts injected will have skin lines and sand grains. Generally, the polishing surface into a mirror is good, in addition to the choice of mold steel, grinding personnel, time, technology will have an impact on the polishing mirror effect, requiring a professional mold polishing master, experience to be particularly rich in order to accurately ...

Plastic injection molding mold will appear a lot of difficulties, injection molding mold is composed of two parts of the moving mold and the fixed mold, the production of plastic products need to use the mold injection molding, is through the injection molding machine will plastic raw materials into the injection mold cavity, after cooling and curing to form the injection molding parts. In the mold manufacturing process, how to deal with the surface of plastic injection molding mold appears gloss defect? The following is the causes and solutions of the surface gloss defect of plastic injection molding mold and. Hope to help you. 1. The mold finish is poor, the cavity surface has rust, etc., the mold exhaust is poor. 2. The mold gating system has defects, should increase the cold well, increase the flow channel, polishing main channel, diverter and gate. 3. The material temperature and mold temperature are low, if necessary, the local heating method can be used at the gate. 4. ...

Electric injection molding machine in the production of injection mold will encounter the situation of injection molding is not filled, there is a lack of glue at the bone position right Angle and fuse connection, here to share some experience. Analysis of glue injection is not filled: 1. The trapped air in the bone position makes the injection molding machine fill up. 2. The filling of the injection molding machine caused by the glue welding line is not filled. Reason analysis of glue injection is not filled: When the injection molding machine is working, the mold gluing method is two-point gluing, and the injection speed is too fast, which is easy to cause the gas trapped at the right Angle of the bone position and cause the filling dissatisfaction; If the injection speed is too slow, it is easy to fill the fuse at the end of the flow. The solution: Multistage injection molding and position switching. In the first stage, the medium speed filling channel was used to pass...

There are many kinds of plastic, many plastic materials melting time are different, because the plastic does not have a specific melting point, the so-called melting point is a melting state of the temperature segment, the structure and composition of the plastic molecular chain is different, so the impact on its fluidity is also different, then in the production of injection parts manufacturers in the injection parts processing temperature control is also very important. 1. Mold temperature Some plastic materials due to high crystallization temperature, slow crystallization speed, need higher mold temperature, some due to control size and deformation, or the need for demoulding, to higher temperature or lower temperature, such as PC generally requires more than 60 degrees, and PPS in order to achieve a better appearance and improve fluidity, mold temperature sometimes needs more than 160 degrees, Therefore, the mold temperature has an inestimable effect on improving the appearanc...

Injection molding is a plastic processing technology widely used in the manufacturing industry, and common types of injection molding include the following: Conventional injection molding: Conventional injection molding refers to the heating and melting of plastic materials into the mold, cooling to obtain a variety of different shapes of plastic products. Conventional injection molding is suitable for the production of various specifications, shapes and materials of plastic products , such as plastic tableware, home appliance shell and so on. Two-color injection molding: Two-color injection molding refers to the injection molding of two different colors or materials of plastic materials in the same mold, so as to form different colors or materials on the same product. Two-color injection molding is suitable for the production of complex plastic products requiring multi-color or multi-material combinations, such as automotive interiors. High-speed injection molding: High-speed i...

Plastic injection mold is an important plastic processing tool, through which plastic raw materials are transformed into products of various shapes and specifications. The principle of injection mold can be summarized as the following steps: 1. Plasticizing and injection First of all, plastic raw materials undergo a series of processing treatments, such as drying, screening, mixing, etc., to become plasticized materials suitable for injection molding. In the heating barrel of the injection machine, the plastic begins to melt and plasticize under the action of heat, forming a uniform molten state. Subsequently, the plasticized plastic is pushed into the nozzle of the injection machine through the pushing action of the plunger or screw. When the plastic in the nozzle accumulates to a certain amount, the driving force of the injection machine stops, and the nozzle of the injection machine injects plastic into the pouring system of the mold. At this point, the pouring system introduce...

1. Injection mold It is mainly used in the production of thermoplastic parts of a common molding mold, injection mold corresponding processing equipment is injection molding machine, plastic first in the bottom of the injection molding machine heating cylinder heat melt, and then in the injection molding machine screw or plunger push, through the injection molding machine nozzle and mold pouring system into the mold cavity, plastic cooling hardening molding, release products. 2. Extrusion mold A kind of mold used to form and produce continuous shape plastic products, also called extrusion molding head, widely used in pipe, bar, monofilament, sheet, film, wire and cable coating, profile processing. 3. High foaming polystyrene molding mold It is a kind of mold for molding foam packaging materials of various desired shapes with the application of flexible polystyrene (beaded material composed of polystyrene and blowing agent) raw materials. The principle is that the polystyrene...
