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. If you are curious then do search other such similar rules for injection molding and make your manufacturing unit an enhanced version of plastic parts and components.

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.

How to Do China Aluminium Die Casting Moldmaking


Die casting and the use of an aluminium mold for plastic injection contributes majority to the production of a large number of metal parts and components. Moldmaking or the incorporation of an aluminium mold plays a major part in giving shape and structure of the final product. The die casting process forces the molten metal into molds and hence requires a mold with an exact specification in order to achieve the desired product in accurate size. The use of an Aluminium mold for plastic injection process has already made a huge success in achieving the target of manufacturing the plastic parts and components according to the client’s requirement with accuracy. So, in this blog let’s just discuss what are those factors which can affect China Aluminium Die Casting Moldmaking.


Draft is the degree to which the mold can be tapered. For ejecting the casting from the die, a precise and accurate draft is needed for smoothing the process, but this doesn’t hold true always as draft is not constant and varies according to the angle of the wall that can play a major role in China aluminum die casting moldmaking. Mold geometry can be less influential on draft. Similarly inner walls can also shrink and require more drafting than outer walls.


During moldmaking there occurs angled and sharp surfaces which can be smoothened by fillets that have a concave junction which can support these angled surfaces. If there are many sharp corners arises during casting then they can be a hindrance for the molds and can increase the risk of production errors, that’s why many molds use fillets to have rounded edges.

Parting Line

To connect different sections of mold, parting line is used. If the parting line becomes dispositions or attains deformity because of a lot of strain then the material can come out through the gap between the mold pieces and can lead to bad moldmaking and wastage of material.

These are some of the most important factors while doing moldmaking but there are some other similar factors which should also be taken good care of while moldmaking process.

How to Choose Low Pressure Molding Machine

How to Choose Low Pressure Molding Machine

Low pressure structural foam injection molding is a gentle injection molding process which makes use of polyamide or polyolefin hot melt adhesives that is designed as a feasible solution for sealing printed circuit boards, batteries and connectors and provides relief for cables. Now the key to the process is the consideration of raw materials and the specialized molding equipment used. It is always wise to talk to the supplier before doing the low pressure molding process regarding in-depth specifications for the machine. Well! There are some other factors which are necessary for deciding for machines and are discussed in brief below.


The mold should be fitted in the clamping area and this is determined by the spacing on the machine restricting mold fitting and removal. The height and depth of the mold should be accommodated well in the stroke of the clamp and there should be a sufficient opening in the stroke for ejecting the plastic component. For free fall ejection, daylight between platens must be greater than mold height and twice the depth of the component to be ejected.

Clamping Unit

The clamping unit should supply locking force so that mold stays tight during low pressure structural foam injection molding process, otherwise, the mold will be broken into parts and the molten material will splash out along the mold split line. Most of the times thin wall sections and deep draw depths require 3-4 tons per square inch, whereas thick wall sections and shallow draw depths require 2 tons per square inch. For calculating the locking force during low pressure molding these values can be multiplied by the projected area of the component.

Injection Unit

The injection unit is important in low pressure structural foam injection molding and must be capable of supplying component shot weight. The total shot weight should not go beyond the 90% of the injection capacity of the machine otherwise, there will be damage. Usually, the injection capacities are written in grams and whenever any other material needs to be processed, then that component shot weight should be recalculated using that material’s specific gravity.
