Why China Zinc Die Casting is Beneficial?


Often most engineers focus very much on the weight of the material when designing components and parts and that’s why zinc is overlooked as it is lightweight. However, there is a huge demand for lighter parts, especially in automotive and gadget industries and to accomplish the task for these industries, engineers choose either aluminium or magnesium for manufacturing parts and components though zinc is more economical. So, if you look on the above parameters, then zinc has no place in the lightweight applications, but if you focus on the overall China zinc die casting process, then zinc could emerge as one of the most favorable alloys for building parts. So now let’s see what are some of the benefits which China zinc die casting can give for manufacturers.

Ability to Cast

No doubt that manufacturers would love if they could feel the fluidity of the zinc alloy. The point that needs to be understood is that as zinc provides greater fluidity, die castings can be thinner, more complex and don’t require any secondary operations which are usually demanded by aluminium and magnesium alloys. The manufacturers could achieve savings as less material is used and also can save a lot of energy which, when otherwise be wasted in melting and recycling.

Less Cycle Time

When the China zinc die casting process takes place, the molten metal is injected into the die for the creation of the part. After the metal gets solidifies, the part is ejected from the tool. Now determining the cooling time in the tool is generally varies according to the alloy and the size of the part. Now the point is how zinc alloys help in achieving less cycle time? Well! Zinc uses the hot chamber die casting that produces four or five shots per minute, whereas other alloys give two or three shots. If you are cautious of having a low cost, then having less cycle time can aid in gaining more savings and this can be achieved from zinc.

Other Properties

China zinc die casting manufacture more strong and sturdy parts and components as the standard zinc alloy help in achieving the highest quality of parts and that too at room temperature. The die casting process is also found to be more in strength as the zinc alloy is inherently having a strength and doesn’t require any secondary aid in comparison to other alloys. Besides this, you can save on much on the overall cost of the part through this process.

How To Design Plastic Part through Plastic Injection Molding China


The Plastic injection molding China offers versatile solutions for manufacturing variety of applications. It also helps in producing high quality parts at low cost. This process is surely far better and beneficial in comparison to other molding processes, but the success of any part depends upon its design. The design can affect a lot in consistency and efficiency and poor design can be more costly and time-consuming. So let’s just discuss few design elements that should be taken into account while applying plastic injection molding China process to achieve quality and precision of the parts.

Thickness of Wall

Now you have the flexibility of reducing injection molded part defects by laying out a smart and well designed wall thickness design. Keep in mind that the thickness of all walls should remain uniform as molten plastic will try to come out of the path of the larger walls leaving the smaller wall areas unfilled. So a thoughtful design layout will play a great role in achieving the accurate and refined injected molded parts.

Corner Transitions

When you are doing high volume production with plastic injection molding China process, the plastic parts having extreme features can become susceptible to defects as molten plastic always flows from the path that offers the least resistance to it and harsh and sharp angles can prevent the molten plastic to move. So, it is very important to keep all corners curved and therefore it is recommended to have smooth corner transitions for better plastic flow.

Weld Lines

These weld lines occur when two sections of a single flow meet. They occur mostly around holes or any other type of obstructions where the plastic flow separates them in order to pass through them and then fostering them to come back together afterward. The injection molded part produced by plastic injection molding China has weld lines and your objective should be to design your part so that the weld lines occur at places where they don’t impact on part’s strength.

Few Rules for Trouble-Free Plastic Injection Molding China

plastic-injection-molding-chinaThough engineers use modern production methods and management systems to manufacture both complex and simple plastic parts and components using plastic injection molding China, still there is always the need to incorporate more accurate solutions and methods to refine the process and make it easy to execute. The practice of using better and suitable plastic material also fosters better manufacturing process. However, reading this blog will help you understand that there are other certain important peculiar rules following which engineers can avoid maximum problems while doing China Plastic Injection molding.

The Wall Should be Consistent

The thickness of the walls of the plastic parts should be uniform as this is the most basic parameter that helps in eliminating many manufacturing problems. The uniform thickness of parts will be able to fit properly together because variation in shrinkage gets minimized. But make sure that the wall thickness should not get exceeded beyond 10% otherwise, a slight disparity can introduce quality problems.

There Should be Proper Gate Location

Just now we have talked about wall thickness in the previous point, but somehow if you couldn’t able to have a uniform thickness, then you should concentrate on having a proper gate location. If due to any reason this gate location is not obtained, then it is not possible to have a uniform pack of the molded part. You know when the most potent location of gate can be achieved is when the melt flows at the thickest part and then flows to the narrower areas.

Knowing About the Wall Thickness

Generally, engineers can’t determine the maximum wall thickness of parts in plastic injection molding, however, the engineers are more concerned towards finding the minimum wall thickness in order to have less expensive cost. This determination of minimum thickness favours two factors like minimum thickness requires less material and also they cool faster. For having the suitable wall thickness, first, do consider the product requirements.

So, these were the most specific rules imbibing, which can aid the engineers in refining the China Plastic Injection molding process and better results can be attained.

Complete Technological Processes of Plastic Injection Molding China


Plastic injection molding China is one of the most feasible manufacturing processes for producing the plastic parts by injecting material into the mold. Excellent use of China plastic injection moldmaking helps in producing the items rapidly and can deliver a large number of identical items efficiently. There are a variety of products produced like high precision engineering products to small disposable consumer goods. In spite of all this, have you ever thought that how exactly the plastic injection molding China is manufacturing such useful and reliable plastic products? Well! There are several processes following which the finished products are achievable. So let’s see what are those technological processes.


The first step of the molding is filling. Time is calculated when the mold is closed and gets filled up to 95% of the mold cavity. It is inferred that shorter filling time leads to better efficiency. If the filling is of high speed then its shear rate is higher. So whenever there is a flow control because of high speed filling occurs, shear thinning of melt is huge and the cooling on thin walls is not obvious, so the effectiveness of speed can succeed.


It refers to applying continuous pressure, thereby compacting mold and increasing the density of plastic in order to avoid shrinkage. As the cavity is being filled with plastic, back pressure is higher. When compaction takes place, the screw of the machine moves very slightly and thereby flow velocity of the plastic is also slower. This flow is called pressurization flow. During pressurization, solidification of plastic gets done by mold wall cooling. The density of material grows constantly and plastic is formed gradually.


Cooling is very important in China plastic injection moldmaking. The plastic products should be cooled so that it can take a definite strength. The cooling is very important as it contributes 70% to 80% in the molding cycle. An adequate cooling can reduce forming time, improves productivity and reduce cost whereas improper cooling time can increase forming time and cost.


This is the last step of the plastic injection molding process. Demolding further improves the quality of the products after they have been solidified. Improper demolding may result in unnecessary stress and the product gets deformed during ejection. There are two types of demolding which should be chosen according to structural features of the products that will produce good quality of products.
