How to Do China Aluminium Die Casting Moldmaking

diecasting

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

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.

Fillets

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.

Mold

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.

China Aluminium Die Casting – Dimensional Accuracy Very Critical

diecasting

Components made by die casting play a vital role in many key industries of the economy. Aluminium as a metal offers a number of advantages. One of them is that the metal is light but quite strong, and one can get very accurate components through china aluminium die casting, provided the molds are of good quality.

Choice of Aluminium as a Material

As mentioned, aluminium is the metal using which many components get made. The process of die casting with this metal requires skill and expertise and is cost effective. The technology has advanced to a great extent, and the moulds are generally made from a steel material. The pouring of aluminium into the moulds under pressure is done to fill the mould, and the casting machines have the provision to set the right temperature at which the casting takes place. The products that come out of the machine are almost perfect and hardly any finishing work has to be done on them. The industries which use the China aluminium die casting machines to manufacture the components, have a choice of machines and the sizes and types of components that will determine the final design and specifications of the machines. What is more important is also the quality of the molds.

Mold also Made by the Machine Maker

The process of die casting requires the machine to be of the best quality and the steel molds also have to be manufactured to perfection. The china aluminium die casting moldmaking companies take care of this aspect also, and the best quality moulds are made by them. In making these moulds, the factors that are considered include dimensional accuracy. To get this right, the China aluminium die casting moldmaking companies first obtain the drawing of the components that have to be made from the moulds. If the customer can give the actual compound also, it helps in making the molds with better accuracy.

Obviously, if the component is being developed for the first time, the customer might not be able to provide the sample piece. The rough piece developed by the design department might not represent the actual specification. The key technical factor kept in view is the coefficient of expansion of the metal of the mold. At the time of die casting, the machine expands when the aluminium is poured and then when the component is taken out after cooling, the accurate dimensions are achieved. Every reliable China aluminium die casting moldmaking company takes care of all these technical parameters to ensure that their customers receive the best moulds. Hence, the components that they then cast using these moulds, pass all tests and are approved by the end users.
