The injection mold is a method by which parts of an object is produced on large scale. Possibly the pen kept on the table near you is made through injection molding. Injection mold maker in China and countries expert in this technique have a good hold over manufacturing sector. There are many processes throughout the injection molding, which requires analyzing the cost, time and raw materials. One of the important pre-molding processes would be molding flow analysis.

Molding flow analysis helps to examine mold design thoroughly. It is pre-analysis of the product manufacturing process with the help of software. Molding flow tries to come to a pre-conclusion of the temperature required to melt the plastics or steel, of the amount required to fill in the cavity and deciding the wall thickness of the object. For example, if due to any reason the wall of the object is too thick it would not cool properly and there would be sink marks that will not look good.

Molding flow analysis is a pre-manufacturing process which not only reduces the cost, it saves the time of the organization and it helps to manufacture parts, objects in a successful way. Suppose without a flow analysis if a prototype is manufactured and it shows some fault, then it needs to be started all again. The design of the tool needs to be changed and there would be enormous wastage of time and energy. Therefore, to control all these mishappenings a molding flow analysis is done.

A company expert in this technique of mold, injection considers flow analysis a necessary pre-requisite. There are various manufacturing companies which are an expert in 3D designing of objects and they are also an expert in designing tool according to the desired wishes. That is why Southeast countries molds and supplies the parts in all over the world especially North America and Europe.

Now, coming again to the molding flow analysis, it examines the flow of melted metal or plastic through channels and tells the quantity to be added or to reduce before manufacturing the parts. It is easy to cut the metal scrap from the object, but it is very hard to add metals due to their characteristics into the parts. For that, a whole new design is carved for the tool which overruns the manufacturing cost and time. All these problems can be averted through proper mold flow analysis.

Injection molding is altogether an expert technique which requires technical knowledge and years of experience in the field. Southeast Asia is considered such an expert especially in plastic injection molds and it is aptly called as an injection molding hub. It supplies, parts being used in healthcare equipment, automotive, electronics and home appliances. Almost everything is being manufactured in countries of this region through injection molding.

Injection molding has made the process of manufacturing an easy task compared to earlier days where the heavy objects were manufactured in one go and where the technologies like flow analysis were not common. Injection molding has turned the pace of economy in a great way.

Making injection mold is a difficult process. Even small mistakes can cost you almost a fortune. Such work should be done with immense attention and prior experience. While making, injection molds one faces many problems like the machine, the mold, but most of the trouble arises due to the plastic. Many people today are opting for plastic and its demand is increasing, but we cannot overlook the difficulties of transparent plastic products in making injection molds. Use of plastic in making injection modules is difficult. There are several reasons behind this. First, the process through which the plastic goes through is a tough one. It passes to the heating cylinder from the hopper on the way into the cavity. After facing such dreadful situations, its shape and size are ought to change. Other reasons are that the valve spring may leak or the heater band might be burned.

The kind of plastic you choose for your mold could also create problems. If you choose wrong plastic it can affect your material adversely. In case you think that all plastics are the same, then you are wrong. They are not. It is important to learn first about your material, your work design about it, its peculiarities. Making all these decisions earlier can be of great help and will also save you the trouble of making changes later.

ABS – The ABS plastic which is generally used has the tendency to get scratch or scars that are clearly visible. During the cooling process, it also has problems sinking. And if you use an opaque plastic, then good luck with it.

Glass-filled nylon – Good thing about the glass – filled nylon is that it can resist many harsh solvents that that could damage other plastics like ABS and polycarbonate but its main con that causes problem is that Glass-filled nylon is extremely vulnerable to sinking. The material design is of no help.

Polycarbonate – Polycarbonate’s price is higher than that of ABS. It also has the tendency to sink. And if there is some kind of defect in your material then it can affect the plastic’s performance.

If you want more strength from the plastic, then you can combine the ABS & Polycarbonate for better results.

Next problem you face from the plastic is due to its color. The majority of the colors in which plastic is available only vary between dark brown or black. You don’t have many options to choose from. After its finishing, the outlook and appearance of the product depend on its final color. If you want, then you can have it spray painted, but that will increase your production cost.

Although the final cost of your product depends on all the investment the choice of plastic plays a major part. In general cases the price is low, but in extreme cases, it can revolve around the figure of $10000 to $12000.
