Design Guidelines For Injection Molding


Injection Molding is one of the most popularly known methods used to manufacture various plastic mould parts such as pipe fitting mould, plastic pallet mould, chair mould, automotive parts mould, home appliances mould and many more. There is some design guidelines considered while manufacturing, such as plastic mould parts.

Design Guidelines:

The manufacturer should avoid small holes, as that will lead to increasing the risks of tool breakage. This will increase your costs, so it is better to consider through-holes in mould parts.

It is difficult to find out the variance in angle or surface consistency. The manufacturer should find out such variance if the design requires an exact angle or surface consistency.

Flatness allowed in both per unit or at reasonable values and is totally calculated as an overall tolerance. This will avoid even a small change in surface variation.

Another key thing is to consider dimensional tolerance. The manufacturer should adjust and balance the machining tool to allow dimensional tolerance. Cutter compensation used to get such tolerance.

To make easy use of plastic mould parts like plastic pallet mould, uniform screw sizes used. This design will help your customers to use it easily.

For manufacturing mating parts, it is better to consider stacked-up tolerance, as this is crucial for relating the male and female joining parts, as otherwise requires a redesign of mating parts. 

All the above guidelines strictly followed by some organizations, One such leading producer in China named HQ Mould manufacturing all plastic mould parts by following the above design guidelines. Thus, choose to buy your products from such professionals.

Design Rules for Injection Moulded Products

Injection Molding is a versatile process easily applied to manufacture all kinds of mould parts. Injection Molding is the industry standard and even custom mould maker makes use of plastic injection molding process to design custom mould plastic parts. Here will see some few design rules to ensure quality and durability.

Maximum Wall Thickness:

The wall thickness of plastic part is directly proportional to both the cooling time of process and the total materials required to produce the plastics. When you decrease the wall thickness, it will help to decrease the cycle time and production costs as well. If the wall thickness is too high, then it will lead to the problems like sink age and war page, where one has to redesign the product again.


If it difficult to force the plastic into a perfect corner, which results in messy product. Thus, mark all the corners to increase the aesthetic and durability.

Applying a Draft:

A draft is a tiny angle ranging from one to two degrees. This angle applied to the mould on the face perpendicular to the parting line. Draft will allow for easy removal of any portions from the plastic mould. Custom mould maker makes use for this design feature to correct the defects in the products.


Ribs are another design feature needed to acquire the overall stability control. Ribs will give greater structural support, as they add as thin wall protrusions. Manufacturer like HQ Mould considers all the above design features, to manufacture their plastics with zero defects.

Choosing The Right Mould Manufacturer

There is no doubt that plastic goods have made life easier for us. Plastic is a material that does not rust or corrodes and it is water resistant as well. Plastic goods can be made to look really attractive owing to the color and the design that can be incorporated with ease which makes it cost-effective when compared to other materials. However, in the manufacturer's point of view, choosing the right plastic mold maker and deciding on the number of items that he is going to make using the mould is crucial in ensuring the success of his enterprise.

Things to ask before you choose a mould maker

Some of the things you should ask the plastic mould manufacturer before you entrust the mould making job include
·         What would be the turnout time to deliver the mould?
·         What would be the technique that would be employed to make the mould?
·         Would it possible to develop a mould tool that matches the annual volume required?
·         Would it be possible to get a warranty on the tool?
·         Would the whole mould be produced in-house or would parts of it be out sourced?
and much more.
The best mould makers
As far as mould making is concerned the chinese are supposed to excellent mould makers whether it is for household appliances, general goods or even highly precise automotive parts. However, it is important to reach out to quality mould makers like HQMOULD with enough track record and technical knowledge to understand what you are looking for and also produce quality moulds at cost-effective prices.

Home Appliance Mould and Mould Makers

Plastic is one material that is used in making a number of products. It is because of the special qualities off plastics such as rust free and corrosion free nature, stain, dust and water resistance, the number of finishes that are possible starting from highly glossy to a matte finish, long life, etc. Above all, it is helpful in reducing the weight of the appliances as well as reduce the manufacturing costs. That is why a number of home appliances feature plastic products. The home appliance mould are created to meet the specifications. This ensures that they are manufactured with precision to perform the functions that are expected out of them.

Mould makers

Though there are a number of mould makers across the world in places like Japan, USA, India, etc, the Chinese mould makers are considered the best. This is owing to their expertise and skill in developing moulds that meet the standards and specifications that are required to make home appliances that are supposed to be functional as well.  The Chinese mould makers like hq mould have a separate R&D department who would be able to ensure that the moulds that are made match the requirements and produces home appliance parts of high- quality cost effective.

The products

When moulds of high-quality are made with due importance is given to the process and the design of the final product, it is possible to get good moulds that can be used to produce quality home appliances like refrigerators, air conditioners, washing machines, dishwashers, etc.

Chinese Mould Maker And The Advantage They Can Offer

Making great moulds that can produce plastic goods of the quantity and quality that is desired is important to ensure profitability for the manufacturer of plastic goods. It also ensures that the plastic goods of good quality would be available at cost-effective prices for the consumers. The mould makers job includes understanding the requirement that is necessary and making moulds that would be good enough too produce goods of the volume that is required on the part of the manufacturer.

Chinese mould makers

There are a number of techniques that are employed in making moulds. It depends on factors such as the
·         Type of product that is to be produced
·         The type of  thermoplastic that is to be used
·         The volume of products that have to be produced using the mould
·         The precision that is required
Though moulds for plastic goods which are quite simple as well as those that require precision are manufactured by mould makers in Japan, USA and India, the Chinese mould makers are considered to be experts in the field. You have a number of mold makers in China who produce quality molds like HQMOULD which include producing the right type of mould for the right product.
Mould maker in China
The plastic mould maker of China is the best you can ask for as they have the technical knowledge and expertise in making different types of moulds. They would be in a better position to suggest the right type of the mould that is required to achieve the expected final product and in the volume that is required by the manufacturer.
