2 Shot Mold Design

Mold design outsourcing is becoming more common as the skills gap widens in the plastic injection molding industry.

If you are like many injection moulding & tool making companies you may be searching for the perfect blend of price, delivery time, quality and support.

If you are becoming frustrated in your search for the ideal mould design service then we might have the answer for you.

Get It Right The First Time

If we had found precision mold design services specializing in high volume products back when we did mold making for thin wall packaging, we believe it would have saved us 5 years of frustrations.

We are not exaggerating. It takes a lot of trial and error to work this stuff out and we suggest, if at all possible, you take the shortcut past that stuff and start doing what works.

To be able to injection mold tens of millions of quality parts consistently and at a profit not only requires knowledge of mold design but also knowledge in the other key areas of part design, machine selection & of course processing.

We can advise you in all of these areas.

If you are ready to take your business to the next level & get the mould designs that will help you achieve the results you want from your business then we invite you to scroll down to the contact form.

Mold Design Services for Molders & Toolmakers

This service is perfect for those injection molders who currently make their own molds & plan to light weight their products by manufacturing injection molds for thin wall packaging products and need help with mold design & machine selection.

This service is also ideal for toolmakers (mold builders) who plan on building moulds for thin wall packaging products (with or without IML) or just need extra design capacity.

Existing Quality Issue

If you have an existing quality issue such as wall thickness variation & want to avoid this issue on your next mold design then we can help you!

Training for Mold Designers

We can also train your mold designers to design thin wall moulds that work properly the first time. Do not waste time thinking you know what you are doing. You do not know what you do not know. Contact us to find out more.

Working Together as a Team

In order to get a design that will be compatible with your business it is critical that we get your input into the mould design.

Such things as expected annual quantity requirement, In-Mold Labeling requirement (IML), mold ejection method & water fitting size need to be discussed before mould design begins.
