Application of two - color injection molding technology in the manufacture of household appliance mold

Two-color injection molding is a technology that can produce a high surface gloss and two different colors inside and outside the plastic parts in one molding. The application of this technology can greatly improve the appearance of the whole machine product. Compared with the ordinary mold and the small two-color/two-component injection molding that has been widely used at present, the large two-color injection molding mold has great differences in product characteristics, mold structure, action sequence, gate setting, flow channel layout and other aspects, and the difficulty is greatly increased.

Application of 3D printing in mold manufacturing

CNC machining is the most commonly used technology in manufacturing molds. While it can provide highly reliable results, it is also very expensive and time consuming.

The five steps of the injection mold production process

First, the process analysis of plastic products. Before the mold design, the designer should fully analyze and study whether the plastic products conform to the principle of injection molding processing, need to carefully negotiate with the designer of the product, has reached a consensus. Including the geometric shape of the product, dimensional accuracy and appearance requirements, necessary discussion, as far as possible to avoid unnecessary complexity in mold manufacturing.

Points for attention in injection molding design

Prepare for the design phase, plastic injection molding process here should first determine what kind of injection parts to do. At the beginning of accepting the design task, if the customer has a simple design drawing, it should be adapted according to the customer's simple drawing and made into the regular parts drawing, repeated communication with the customer to determine the drawing. At the same time indicate the specification and technical requirements, production yield, sample shape scale, surface roughness, volume and quality. Review cases, collect relevant information, sort out injection molding design data, molding process, molding equipment, mechanical processing and special processing data, ready for use.

What conditions should injection molding have?

Injection molding is a wide range of knowledge, technical and practical industry. In the process of injection molding production, plastic raw materials, color powder, mouth material, mold, injection molding machine, peripheral equipment, fixture, spray, all kinds of auxiliary materials and packaging materials, etc., which bring a lot of workload and certain difficulty to the management of injection workshop. So, what conditions should injection molding have? Let's look at it briefly.

How much do you know about finishing in die making?

Die parts processing, according to the appearance and shape of parts, parts can be roughly divided into three categories: plate, special-shaped parts and shaft, the common process is roughly: rough processing - heat treatment (quenching, tempering) - fine grinding - electrical processing - pliers (surface treatment) - assembly processing.
