    2.1 Unrestricted gate. Unrestricted gate is also called straight gate. Its characteristic is that the plastic melt flows directly into the cavity, the pressure loss is small, the feeding speed is fast and the molding is easier, and it is suitable for all kinds of plastics. It has the advantages of good transmission pressure, strong pressure maintaining and shrinking effect, simple and compact mold...
  • Commonly used materials and attention in CNC prototype processing Aug 21, 2020
    CNC processing is a very common processing method for prototype parts. The commonly used materials are: ABS, POM, PMMA (Acrylic), Nylon, PC, PP, PA, BT, PVC, etc. Aluminum alloy, copper, etc. After the workpiece is clamped, the digital control system can control the machine tool to automatically select and change cutter according to different procedures, automatically change the spindle speed, fee...

    2.2 Limit the gate. The cavity and the runner are connected by a channel with a short distance at one end and a small section. This channel is called a restrictive gate, which limits the thickness of the gate and rapid solidification. The main types of restriction gates are: 2.2.1 Point gate. Point gate is a round gate with extremely small cross-sectional size. The characteristics of the point gat...

    How many you know about the ultrasonic plastic welding ? Sep 21, 2020
    How many you know about the ultrasonic plastic welding? Plastic welding refers to the method of heating the contact surface of two plastic parts to melt at the same time, so that they are combined into a whole connection method, only applicable to the thermoplastic joint welding, we can use electrode or not use electrode. When using the welding rod, the end face of the welding end shall be made in...
  • What are the precautions for mold polishing? Sep 04, 2020
    Mold polishing has two purposes; one is to increase the smoothness of the mold, so that the surface of the product from the mold is smooth and beautiful, and the other is to make the mold easy to release, so that the plastic will not be stuck on the mold and cannot be taken off. Mastering a reasonable polishing method can improve the quality and service life of the mold, thereby improving product ...

    2.2.3 Side gate The side gate is also called the edge gate, which is generally opened on the parting surface and feeds from the outer side of the cavity (plastic part). The side gate is a typical rectangular cross-section gate, which can easily adjust the shear rate and gate closing time during mold filling, so it is also called a standard gate. The side gate is characterized by simple gate cross-...
  • Plastic product surface treatment process-painting Sep 21, 2020
    Plastic product surface treatment process types: silk screen, pad printing, painting, electroplating, hot stamping, laser carving, water transfer printing, etc. The purpose for painting are improving appearance and functions, such as friction resistance, corrosion resistance, radiation resistance, acid and alkali resistance, fire resistance, increased strength, etc. The main painting processing ar...

    .2.5 Fan gate Fan-shaped gate is a gradually expanded gate, which is a variant of side gate, and  used to form large-width plate-shaped plastic parts. The gate gradually widens along the feed direction, and the thickness is gradually reduced to the thinnest. The plastic melt is uniformly distributed in the width direction, which can reduce the internal stress of the plastic part and reduce th...
