here are two main purposes for polishing the mold, one is to increase the brightness and beauty of the plastic mold. The two is to make the die easy to die out. In the process of polishing, crude oil stone is used for rough grinding of the machined mold cavity surface, grinding to the tool mark, and then using the fine oil stone to get the coarse oil stone to reach the trace, then the fine sand paper is […]
Hot runner technology, with its unique technical advantages such as saving cost and shortening molding cycle, has become an important direction in the development of plastic injection molding technology. In Europe and America, most of the injection production relies on hot runner technology, but there are few enterprises in China using this advanced technology. But with the further development of China’s mold industry, this technology will be gradually promoted and widely applied. How to choose the appropriate hot runner […]
Why use hot runner?
The quality of Multi-cavity plastic mold is not the same.
Thin Wall of plastic products have large deformation.
Use rate of runneris low.
It is very difficult tofill the plastic mold.
The advent of hot runner technology has provided a more comprehensive solution to these problems. Generally speaking, hot runner has the following advantages:
In the runner, the pressure loss is small, the plastic fluidity is good, the temperature is uniform, the internal stress of the product will be reduced, the […]
As we all know that the mould produced by mould factory is closely related to people’s life. According to statistics, in daily life, we use 90% of the plastic products are made by injection molding. So what is the advantages of mold factories? What do we need to consider when we are looking for a mold factory?
mold making
First of all, we should understand the enterprise qualification, which is the most direct way to prove the strength of an enterprise. Second, to understand the capacity […]

One component of the plastics manufacturing industry that’s on the rise is large part injection molding. This industry has come a long way. Many large parts that used to be made of wood or metal are now made of injection molded plastic. Producing larger and larger injection molded parts is easier and more efficient than it’s ever been. It’s also more sustainable, too!
Before we cover the benefits, you need to evaluate the plastics manufacturer you partner […]
Plastic injection mold is a mold used to form parts of thermoplastic products. Its forming features: after the plastic is heated to the flow state in the injection molding machine barrel, the closed mold is used to pass the viscous plastic in the barrel through the machine nozzle with high pressure element, and it is injected into the mold and enters the mold cavity through the pouring system and fills the mold cavity. The product is then molded by […]
Plastic injection molding is one of the most cost effective ways, if not the most cost effective way, to manufacture parts. However there are some factors to consider when you decide whether plastic injection molding in China is a competitive option for you.
1.Time
The adage “time is money” has been true since recorded history. So considering the time it will take to complete an injection molding run is crucial. An injection molding job can run from 4 to 12 weeks, this doesn’t include […]
When you begin a plastics design and engineering project, the goal is to create and manufacture a quality injection molded component. To accomplish that, you’ll want to consider front-ending some essential parts of the designing and engineering process so the actual manufacturing process will operate smoothly. This will ultimately save you time and money in the long run.
Select The Right Material
This may be the most straightforward rule of the previous four. Determine what material is right for your part. Is […]
Double color mold: two kinds of plastic materials are molded on the same injection molding machine, and are molded in two times, but the products only die once. Generally, this molding process is also called double injection molding, usually by a set of molds, and a special two-color injection molding machine is needed.
Overmold: two kinds of plastic materials do not have to be injected into the same injection machine and are molded in two times. After taking out the […]
Plastics In-House Engineering Capabilities
Most manufacturers get components and assemblies from a variety of vendors. It’s not cost-effective to produce these items in-house. However, your vendors don’t have to be just glorified warehouses that provide pieces of your products. A full-featured manufacturing engineering services partner offers not just manufacturing but also engineering design and support.
Manufacturing and Engineering Services
Obviously your first concern with manufacturing engineering services is their ability to manufacture. You need to be sure the company has the capacity […]
