Mould Design in Plastic Injection Moulding 

Injection Moulding is an extremely versatile procedure.  It can be utilised for virtually any product. Injection moulding is the industry standard for manufacturing components for products.

There are some limitation needs to consider. Here are the rules to follow when designing your product to make sure quality and durability:

Wall Thickness

Keeping your walls thin will ensure a faster cooling rate and less materials used. Lower cooling rate and less material used will result in a shorter cycle time. This allows you more parts in a shorter amount of time, for less production cost

To strengthen parts, ribs are more effective than thicker walls. Adding ribs at right angles to a wall will add considerably to its overall strength. It is a common mistake to thicken the walls of a design to achieve this effect when ribs are a cheaper and more effective option.

Ribs should be about half the main wall thickness. There can be some leniency here, but not too much or the ribs will be completely ineffective. Half is the generally accepted standard and is more than enough to increase a wall’s strength.

Coherence

Try to make your design uniform throughout. That is, wall thickness, rib thickness and corner radii, for instance, should all be the same values. This will help the part to cool uniformly.

Corners & Edges

Corners could be an issue in a mould and will not come out flush. It is difficult to form plastic into a flawless corner. The outcome will look amateurish and messy, not to mention the power of the components can be compromised.

Corners and edges should be rounded wherever possible. Sharp edges do not always come out perfectly when the part is ejected from the mould.

Add a slight angle to the sides of your mould to allow easy release. A one- or two-degree angle should be applied to the mould on the face perpendicular to the parting line. This will allow for easy removal of the part from the mould.

Ribs

These are structural factors for your component, utilised for general stability control. Ribs are thin wall protrusions which extend vertically from a plane or wall. Adding ribs instead of thicker walls will provide greater structural support.

Bosses

These are empty, cylindrical protrusions. These are normally integrated in a style for accepting screws or other mating parts of your style. Making sure these are secured by attaching them a wall. Putting in ribs will means the bosses will stay straight as well as accommodate the part it was made for without an issue.

External Undercuts

A depression or protrusion in the exterior of the mould – the cavity half – could create issues if trying to divide parts from the mould. Adjust the parting line to lodge this.

Internal Undercuts and Overcuts

Related to external undercuts, these depressions or protrusions are within the mould – on the centre half. Adjust the parting line to lodge this.

Protrusions on the part that will snag on the mould core or cavity when it is opened can make it impossible to remove from the mould.

Threads

When your mould has a thread, always position it vertical to the parting column. This will make sure that the delicate thread isn’t damaged. It’s better, preferably, to not comprise a thread at all in the design. Making your design simple will lower the odd of something going wrong.

Injection mouldingdesign makes a superior product. The myriad possibilities far outdo the limitations. Designing for an excellent injection moulded part is the core of the design process.  These restrictions are the guidelines for making a flexible end product.

Colour use

Where possible, use lighter colours for your moulds. The mould is already cool when the molten material is being injected. As such it begins the setting process immediately and will sometime leave setting patterns. Using lighter colours will help y.to hide these patterns.

Injection mouldingis the industry standard for creating lasting, quality parts. To be able to take advantage of this technology your design must meet its minimum requirements. Small considerations are all it takes and the result is a successful product that will meet all of your quality needs.

Control of Injection Molding Parts Processing Temperature

There are many kinds of plastic, many plastic materials melting time are different, because the plastic does not have a specific melting point, the so-called melting point is a melting state of the temperature segment, the structure and composition of the plastic molecular chain is different, so the impact on its fluidity is also different, then in the production of injection parts manufacturers in the injection parts processing temperature control is also very important.

1. Mold temperature

Some plastic materials due to high crystallization temperature, slow crystallization speed, need higher mold temperature, some due to control size and deformation, or the need for demoulding, to higher temperature or lower temperature, such as PC generally requires more than 60 degrees, and PPS in order to achieve a better appearance and improve fluidity, mold temperature sometimes needs more than 160 degrees, Therefore, the mold temperature has an inestimable effect on improving the appearance, deformation, size and mold of the product.

2. Injection pressure

Melt to overcome the resistance required to advance, directly affect the size of the product, weight and deformation, different plastic products need different injection pressure, for materials such as PA, PP, increase the pressure will make its fluidity significantly improved, injection pressure size determines the density of the product, that is, the appearance of luster. It has no fixed value, and the more difficult it is to fill the mold, the pressure of the injection part increases.

3. Barrel temperature

The melt temperature is very important, and the injection cylinder temperature used is only a guide. The melt temperature can be measured at the nozzle or by air injection. The temperature setting of the injection cylinder depends on the melt temperature, screw speed, back pressure, injection volume and injection part cycle. If you do not have experience working with a particular grade of plastic, start with the lowest setting.

For ease of control, the cylinders are divided into zones, but not all are set to the same temperature. If operating for a long time or at high temperatures, set the temperature in Zone 1 to a lower value, which will prevent premature melting and diverting of plastics. Ensure that the hydraulic oil, hopper sealer, mold and injection cylinder are at the correct temperature before the injection parts begin.

4. Melting temperature

Melt temperature plays a major role in the flow performance of the melt, because the plastic does not have a specific melting point, the so-called melting point is a melting state of the temperature segment, the structure and composition of the plastic molecular chain is different, so the impact on its fluidity is different, rigid molecular chains are affected by temperature more obvious, such as PC, PPS, etc., and flexible molecular chains such as: PA, PP, PE and other fluidity by changing the temperature is not obvious, so should be adjusted according to different materials to reasonable injection molding parts temperature.
