We assist with material selection and component design to optimise manufacturing. Supply Concepts will work closely with your project manager as part of your design team and as a strategic sourcing partner. We perform flow process simulation to optimise part concept and tooling design. Gate design analysis, filling, packing, runner balancing and cooling are all optimised. Prototypes are made to validate designs and sample production runs are performed as part of the testing stage to evaluate the final tooling and part designs. 

There are many benefits in building your plastic injection moulding tool and parts in Asia. We offer you a wide range of types of steel for tooling including German, Swedish and American grades for particular cores to achieve the desired results. Tools can be made for both short or long life spans, depending on the product to be moulded, the quantity to be produced and the cost analysis associated with the project.

List of plastic processes

Gas assist injection moulding GAIM

This process utilizes high pressure nitrogen gas to produce hollow injection moulded components resulting in lower weight, shorter cycles and reduced visual sinking. Variants of this process include “external gas moulding” and “internal gas moulding”. These processes allow more design freedom and flexibility. It also allows discreet coring out of a thick product, thicker ribbing and can also eliminate sink marks.

 

Water assist injection moulding WAIM

This process is used in the manufacture of complex hollow items leaving a relatively uniform wall section. Water is used to displace polymer melt and provide the packing pressure during the cooling phase of the cycle. Typical examples; manifolds, elbows and water pipes.The suggested advantages of WAIM over GAIM are:

-Thinner residual wall thickness (RWT) - lower material usage.

-Higher cooling rate - particularly where water is circulated.

-Improved internal surface finish.

This process has been most popular in automotive components that are typically thick sectioned. For example: conduits that convey fluids around an engine and car door handles would utilize this process.

Metal injection moulding MIM

MIM is an advanced manufacturing process for forming small, complex, high-precision and high performance metal parts. It is a development of the traditional powder metallurgy (PM) process and has several key advantages. In the PM process, parts with undercuts or projections at right angles to the pressing direction cannot normally be directly made. The MIM process substantially removes this limitation.

 

Co-Injection Moulding, 2 component moulding, multi-component moulding

Similar to injection moulding but with multiple extruders to produce a single component from two 2 or more different parent materials or colors. Typical applications are soft over-moulding to produce seals or ergonomic soft-touch handles. Examples are : screwdrivers, soft-grip handles, cup-holders and  toothbrushes.

 

Thin wall injection moulding TWIM

Thin wall moulding is defined as a wall thickness of less than 0.025 in (0.62 mm) or a flow length to wall thickness ratio of greater than 200. When compared to standard injection moulding, high melt flow materials are used (30-60 MFI) along with accumulator assist injection and higher injection speeds/pressures. Stack moulds are common.

 

Micro moulding

Recent advances in miniature moulding technology has seen major growth in the area of micro moulding for electronics and medical applications.

 

Thermoplastic Injection moulding

Thermoplastic Injection moulding is the most widely used of all plastic processing methods. Injection moulding offers the lowest piece prices available, but tooling prices are generally the highest. The injection moulding machine reduces pelletized raw material into a hot liquid. This "melt" is forced into a cooled mould under tremendous pressure. After the material solidifies, the mould is opened and a finished part is ejected.

 

Thermoset injection moulding

Thermoset injection moulding is similar to thermo-plastic injection moulding except that uncured thermoset resins are mixed, injected, and held in a heated mould until cured. As with thermoplastic moulding, the price per piece can be low, but the tooling prices are generally higher.

 

Blow moulding

This method is typically used to create hollow parts; jars, bottles, containers, etc. Part prices for this style of plastic and rubber services are generally higher than injection moulded parts, but, lower than rotationally moulded parts. Tooling costs are moderate.

 

Rotational moulding

Rotational moulding uses hollow moulds filled with powdered resin. Low tooling costs and higher piece prices are typical of this process.

 

Compression moulding

Compression moulding services use a slug of hard media pressed between the two halves of a heated mould. After being formed, the part is air-cooled. Both tooling and piece part prices are moderate.

 

Thermoforming plastic moulding

Thermoforming plastic moulding uses sheets of pre-extruded rigid plastic as the feed material. These are heated horizontally and sucked down into hollow one-piece tools.

 

In-mould labelling IMD

(Also referred to as In-mould decorating) Mainly used in injection moulding. Robotically placed individual pre-printed decorative labels are loaded during each machine cycle into the mould tool. To assist adhesion during the closing and material flow stages, the label and tool is electrostatic charged.

 

Plastic welding

Plastic welding – various plastic welding processes are employed depending upon part geometry, size and polymer used. Ultrasonic welding, hot-plate welding, vibration welding, laser welding and spin welding can all be used.

 

Structural foam moulding

Structural foam moulding is a term commonly used to describe components made by the injection moulding process that have a cellular core in which the outer surface is denser than the inner layers. The core of the moulding is of a honeycomb nature and less dense than the outer surface. Can also be referred to as microcellular injection moulding (MuCell). Applications include - Wine corks, Energy absorbing foam, low weight products, impact absorbing pads.

 

Moisture conditioning

Some plastics, including nylons, will absorb moisture from the atmosphere, which alters their physical properties. Properties affected include brittleness and dimensional stability. Moisture absorption can be as high as 2% of a products weight. A pigment is often applied during the moisture conditioning process to identify treated parts.
