Causes of color defects in injection parts Feb 15, 2019
(1) poor mold finish, mold surface rust, mold exhaust is bad. (2) if the casting system of the mold has defects, the cold feed well should be increased, and the flow passage, polishing mainstream passage, diversion passage and gate should be increased. (3) the material temperature and mold temperature are low, if necessary, local heating method of gate can be used. (4) low processing pressure, slo...

Requirements of Thin-wall Injection Molding to Mold Feb 15, 2019
Speed is one of the key factors for the success of thin-wall injection molding. Rapid filling and high pressure can inject molten thermoplastic material into the mold cavity at high speed, to prevent the gate from freezing. If a standard part fills in two seconds, the mold thickness will be reduced by 25%, and the filling time may be reduced by 50% (saving 1 second in time). When thickness decreas...

What is the effect of mold flow analysis on the mold? Feb 22, 2019
1. You can know if the part is full. The analysis can also provide other useful information such as the required injection pressure and clamping pressure. 2. You can know if the part has a filling problem. Many filling problems, such as short shots, bubbles and unbalanced filling, can be determined by careful analysis of the filling curve. Mold flow analysis allows you to change the position of th...
What is double injection mold? Mar 02, 2019
Double Injection Mold, also known as two material molding, 2 shot molding or 2K molding, is a manufacturing process used to produce complicated molded parts from two different materials. Two kinds of plastic materials are injected on the same injection machine, and they are formed twice, but the product is only molded out at once. This injection molding is usually completed by one mold and require...

Venting of plastic injection molds Mar 02, 2019
It is well known that the exhaust of injection mold is a problem that cannot be ignored in the mold design.Mold inner product set in the normal production of gas mainly has the following sources: 1. The feed system and the entities of the air in the cavity. 2. The plastic contains moisture evaporation and water vapor generated at high temperature. 3. The gas produced by plastic decomposition. 4. S...

Procedures of Plastic Thermoforming Mar 15, 2019
The basic process of hot thermoforming is: clamping, heating, molding, cooling, demoulding. Among them, molding is the most important and complex. Plastic thermoforming is mostly carried out on the moulding machine, which varies greatly with the different methods of thermoforming. Not all kinds of moulding machines are required to complete the above five processes, and it can be chosen accor...

What is Over-Mold? Mar 21, 2019
When We say "Over-Mold" means the secondary injection molding of the product. The main product consists of two parts, one refers to the plastic inside, and the other refers to the soft part outside. At the time of mold manufacturing, a plastic mold, that is, a main hard mold, is first manufactured. After he cools naturally, he puts it in another pair of molds and re-inserts the m...

Undercut in Plastic Mold Mar 29, 2019
In some plastic products, there are undercuts. If it is a small undercut, and the requirements of shape and size accuracy are low, or the plastic material has sufficient plastic deformation and toughness, the parts can be ejected/ demoulded by force. According to the different structures and requirements of plastic parts, the slider and lifter mechanisms is adopted to solve the problems in m...
