  List of technical points for production, R&D and quality control of plastic toys Whether it is a toy designer or a toy company, in order to truly professionally engage in toy industry, in addition to timely market-related dynamics, it is also necessary to pay attention to basic design knowledge of toys, such as plastic toy production, research and development and quality control technology. Below, for main points of production of plastic toys, HEYA MOLD one by one for you to analyze: First, production process Generally speaking, production process of plastic toys is roughly as follows: separate molding of injection molded parts, silicone parts, separate forming of hardware and PCB parts, other decorative parts of clothing, final assembly, inspection, and packaging. Molding of injection molded parts: Prepare toy moulds, pellets, toner/color masterbatch, stabilizer, plasticizer, mold release agent, etc., and generally add degraded material that is broken by injection mould...

 Correct choice and use of mold spring - mold parts for plastic molding manufacturing First, basic knowledge of spring In a set of plastic molding, more elastic materials are needed, including various springs, superior rubber, and nitrogen springs. Different elastic materials are used in different plastic molding manufacturing according to different needs. For example, bending and punching can be done with ordinary flat wire springs, such as brown springs, also known as brown springs; excellent glue is generally used for drawing molds, shaping molds, or flatness. Spring includes flat wire spring, wire spring, etc. Purpose of spring is to remove and press material in plastic molding, magnitude of spring force is related to whether mold production is smooth and whether product is qualified or not. Spring force is small, which may cause various problems in plastic molding manufacturing such as product deformation, mold not to be stripped, products not good to be taken out from mo...

 Technology of two color injection molding that every technician must to know! Two color injection molding technology is also called double-material plastic injection molding technology, which is a technology that uses two plastic materials to mix and mold plastic products. Technical connotation is actually using a mold assembly to shape and weld molding work in the mold. Therefore fundamental principle is to plasticize two different plastic raw materials, and then use mold for welding installation, in order to achieve purpose of two shot injection molding.   T wo shot injection molding technology type 1.1  Core Rotary two color injection molding  t echnology This technology is also known as transfer molding core two shot injection molding technology. Technical principle is to inject the first raw material plastic by injection equipment, inject it into small hole of mold, and become the first plastic after molding. Then mold is rotated by 180...

 36 experience of two-color injection mold design and dual shot injection molding 1.  Basic principles of two-color injection mold design : (1) 1 time for hard plastic and 2 times for soft plastic; (2) 1 time for transparency and 2 times for non-transparency; (3) 1 time for plastic with high molding temperature and 2 times plastic with low molding temperature; Above is basic principle of making a dual shot injection molding, otherwise mold will be undone; in addition, when sealing glue, try to use sealant instead of inserting sealant, even if it is recommended that customer modify product as much as possible by using sealant; 2.  Guide bush guide bushing must be symmetrical top and bottom, left and right . Front and rear modes are symmetrical. 3.  Back mold should be rotated 180 degrees, and front mold does not move . 4.  Spacing of products must be based on spacing of nozzles of plastic injection molding machine...

The role of mold flow analysis Have you ever encountered such a situation where a set of molds were tried repeatedly, but they just couldn’t figure it out. These problems were changed, and other problems occurred, such as changing the gate position, changing the runner gate size, and modifying the product. To meet the molding requirements, repeated mold trials are very wasteful. When the problem is serious, the mold cannot be modified and can only be scrapped. The mold needs to be redesigned and manufactured, which affects the delivery time. The above problems are common occurrences in mold factories. The fundamental problem is that the mold flow analysis (CAE) is not in place. Mold flow analysis technology can simulate and evaluate the molding process of plastic parts on the computer before mold processing. If there is a problem with the design plan, the revised plan can be input into the system again for analysis until it is satisfied. Therefore, a good application of this technology...

  Tips for plastic rattan stool mold manufacturing Plastic rattan chairs  and stools are very popular nowadays as it is durable, beautiful and with good texture. If want to produce high-quality chairs and stools, we must ensure that all aspects of the mold are optimized to maximize productivity. As is well known, the smooth surface of daily necessities is an important manifestation of aesthetics. It is dangerous to make the parting line of the chair and stool not smooth. In order to avoid sharp edges, we must pay attention to many aspects in the chair mould and stool mold production process. What is the processing for rattan stool mould making? Simply first, from rough machining to steel hardening, after steel hardened, we start the CNC milling. We will leave a tolerance of 0.3mm under normal conditions, and then wait the steel stress released, we start the finish machining. Machine operation is very important. Two points need note: 1. we need cool the area where needs CNC mil...

  Flower pot mould In the future, there is a lot of room for development, because the modern people's lifestyle is slowly transformed into self-cultivation, and flower cultivation has become a hobby in their lives. Flower pots are produced through injection molds, with short production cycle, large output, and long tool life. . Flower pot molds will be manufactured by more and more people. 1. The flower pot mould has the bottom touch perforation and the side wall touch perforation to achieve water leakage (to prevent too much watering at one time to make the flowers rotten). The bottom leakage design is directly through the direct core cavity, and the punching cannot be too small, because it is too small to require high-precision machining, and the cost will increase. The sidewall leakage design uses the cylinder core to achieve the collision, which is a challenge to the complexity of the mold structure. The production cycle of the product will also be lengthened. 2. The economic b...
