What are the ways to reduce the cost of injection molding?

There are two main areas where injection molding costs can be reduced: investment costs (such as mold production) and part costs. Next, we will share how to reduce the cost of injection molding.
1. High efficiency mold design: high efficiency mold design can make parts as easy as possible to produce, package and realize, while Zui greatly reduces errors. This means following the design Zui principles, such as adding a proper draft angle (or taper) to the part to facilitate […]

Silver wire of common problems in injection molding

Silver wire is a silver white stripe formed by low molecular volatiles, water vapor and other gases on the surface of injection molded parts.
1. Raw materials are wet and contain too much water
2. Residual moisture in mold cavity
3. There are residual lubricating oil and mold release agent in the mold cavity.
4. Foreign matters mixed in during batching
5. The wall thickness of plastic parts is uneven. When the molten material flows from the thin wall to the thick wall, it […]

How to control the barrel temperature effectively in the process of injection molding

In the process of injection molding, ensure that the working temperature in the barrel of the injection molding machine can be kept within the set range according to the requirements of the injection molding process. Accurate temperature control in the precise injection molding is conducive to improving the product quality and the utilization rate of plastic materials, which is very important in the injection molding.
Different plastic products are produced by injection molding. The parameters of the barrel temperature object […]

Why is it so expensive to open a set of plastic molds?

“Why is the cost so expensive” this is probably the majority of customers aspirations! But in my opinion, open a set of plastic mold is expensive to follow.
1) plastic mold belongs to customized products, rather than ordinary standard parts.
2) the difficulty of product structure determines the difficulty of mold processing. The more complex the mold processing, the more manpower and material resources spent.
3) the cost of the mold steel used in the plastic mold is also an important factor […]

How to avoid the damage in the processing of plastic mould

For some mold manufacturing process is not perfect or not professional plastic mold manufacturers make plastic mold manufacturing process will appear some mold damage. So how can we avoid these injuries?
Mingyang Yutong plastic mould factory
1. Design rationality of plastic mold structure
In case of meeting the use requirements of plastic mould, the structure shall be as simple as possible to facilitate molding. The wall thickness shall be as uniform as possible to avoid stress and deformation of plastic parts.
2. The […]

What is the function of plastic material and glass fiber in injection molding?

Thermoplastics do have natural mechanical properties, which can give strength, durability, impact resistance and other benefits to plastic molded parts. Adding glass fiber to plastics can further enhance the performance of the resin.
One of the problems that may occur in injection molding of materials with glass fiber is that the brittleness of the parts is increased due to the significant improvement of the strength and rigidity of the parts.
However, if the glass filled plastic parts do not need to […]

What is the most important factor in choosing injection mold?

Today we are talking about the old saying, “is the price of injection mold closely related to the quality?” Most people in the purchase of injection mold, the price factor is very important, even the only factor to consider, of course, appropriate cost control is beyond reproach, but in addition to the price should also pay attention to other factors, otherwise the final choice of products may not be very suitable for themselves.
The choice of injection mold depends on […]

Application of injection molding in plastic gear

With the development of plastic industry, plastic products are more and more widely used in all walks of life with its unique advantages. At the same time, the important position and role of plastic mold injection molding in production and manufacturing are gradually recognized by more and more people.
Gear, a special mechanical part, is gradually replaced by plastic. Compared with traditional metal gear, plastic gear has the following advantages:
① Plastic gear is lighter than metal gear, which can reduce […]

How to determine the feeding way of the rubber inlet of the plastic mold

The injection way of plastic injection mold mainly includes point injection, diving injection, needle valve injection and direct injection. A reliable manufacturer will be based on the cost of plastic mold. The mold cost will vary greatly with different rubber inlet. The cost of hot runner rubber inlet and spot rubber inlet is higher than that of ordinary diving and direct rubber inlet. We should ensure the quality of plastic mold and the requirements of plastic products, at the […]

Understand the long-term benefits of plastic injection molding

The rapid production of plastic parts is possible with the development of many technologies. Among them, plastic injection molding is recognized by most people. This technology has many advantages, although it has some limitations. Now, we will study the benefits of this plastic manufacturing technology:
Reduce manufacturing costs
Plastic products can be produced in large quantities or even at cheaper prices. Because now production is automated. Labor costs have fallen dramatically, reducing production costs and providing customers with cheaper products in […]
