Also sometimes called rotomoulding, this method involves the resin or liquid being placed inside the mould and then being rotated at high speeds. The liquid then evenly covers the entire surface of the mould to create a hollowed part with all the walls evenly thick. After the mould is cooled and the liquid plastic has taken its new form it is then taken out of the mould.

The moulds that are used in rotational moulding are highly intricate to make products customizable and changeable. This can include things like special inserts and curves as well as logos and slots. These can be placed into the mould to change the final product.

This method involves the raw liquid plastic being poured into a heated mould and then being compressed together to form the desired shape. The high temperature of the entire process ensures good strength in the final product. The process is finished off by cooling the liquid plastic so that it keeps its form before being trimmed and removed from the mould.

The most effective use for this method is when you want to make plastic replacement parts for broken metal parts. The reason for this is because the high-temperature method makes for a very strong and durable end product. Even though it is plastic, it is a strong and low-cost replacement for the metal parts.

When it comes to the pricing the moulds can be very expensive because they need to be steel or aluminium for higher strength and durability. Luckily, as with most methods, the cost per unit drops drastically depending on your production volume.

These 5 types are extrusion moulding, compression moulding, blow moulding, injection moulding and rotational moulding. We will look at the details pertaining to each of these methods so that you can decide which one will be the most effective for you to use.

With extrusion moulding, hot melted plastic is pressed through a shaped hole to create a lengthy shaped plastic part. This customizable shape that the liquid plastic gets pressed through is called a die. This die is custom made for the particular outcome that is desired. It is almost like pressing dough through a press to make shaped cookies.

The machine heats up the raw plastic until it becomes liquid and then injects air into it like a balloon. The plastic is blown into a shaped mould and as it gets bigger it presses against the mould walls and it starts to take its shape. After the liquid balloon fills the mould it is cooled to keep its shape. The process is very fast and can produce up to 1400 pieces in a 12-hour work day.

Regardless of the application, injection-molded parts and products are expected to perform to stringent quality and regulatory standards.

This is a common method to produce a high volume of plastic parts like car parts or even parts for surgical applications. Products can also be made with increased flexibility to suit the needs of designers or engineers.

When using this method your outcome product will continuously have the same shape along the length of it. These can be things like straws or PVC pipes. These types of parts can be made at very high volumes because it can just keep producing the same shape without end.In comparison, this type of moulding is low cost because the equipment is fairly simple and can have high productivity. The downside to this method is that you are very boxed in when it comes to the variety of parts you can make.

The other forms of plastic moulding also use extrusion so get the raw liquid into the moulds, the difference here is that other methods use the moulds to make the desired shape and here the extrusion itself is making the shape with the use of the die’s shape.

The result? Consistent, high-quality injection-molded plastic parts and devices that meet end-user expectations and drive competitive advantages for OEMs across many industries.

Injection Moulding is fairly similar to extrusion moulding. The difference here is that with injection moulding the melted plastic is injected directly into a custom mould. The injection is under high pressure so that the mould is filled and a solid part is made. As with the other methods, after the mould is filled, the plastic is cooled as to keep its new shape and then the mould is opened.

Plastic moulding is the process of pouring liquid plastic into a certain container or mould so that it hardens in that customized shape. These plastic moulds can then be used for a wide range of purposed. There are 5 types of plastic moulding that is considered to be the most effective and most popular.

The scientific molding process dictates the use of material science to define and unify the stages of injection molding. Advanced instrumentation records data and parameters so manufacturability is easily replicated across production runs and equipment.

Blow Moulding is mostly responsible for producing products like plastic bottles, drums, cases and even fuel tanks. If your required number of parts is around the hundreds of thousands then this method is perfect for you (like a soda company).

cavities and the surface finish. When you are mass producing then this method is ideal because the cost per part will be very low.

This is a fast and economical friendly option with the mould prices ranging somewhere in between injection moulding and rotational moulding.

Experienced engineers — like those on the Kaysun team — are integral to a successful scientific molding process. They are trained to adhere to these six essential steps and have the expertise to optimize the process window for your specific project.

The most common use for this method is for big and hollow parts. These parts include car parts, bins, kayaks, road cones, pet houses and storage tanks.

With blow moulding, the custom plastic parts come out hollow and thin-walled. This method is ideal for when the plastic part has to have uniform wall thickness. This is very similar to the process of glass blowing.

While thorough, comprehensive, and unique to each complex application, scientific molding can be broken down into six steps for highly specialized engineers to follow.

Ensuring successful outcomes requires the application of scientific molding principles by experienced injection molders and trained engineering teams throughout the molding process, especially during development and production.

The tooling costs with rotational moulding are lower than other methods like injection and blow moulding. This makes for lower start-up costs and more effective production costs even at low volume production.

This method is very material efficient and very little goes to waste making it more economical and environmentally friendly.
