Why Innovative Products Are Designed & Manufactured With Northwest Plastics

Looking for a company to bring your idea to life? Northwest Plastics has helped many businesses fine tune their product idea, designed their product, saved on product launch costs and brought their concept to life. We have even partnered on product development. Let's put our 40 years experience to work for you.

What We Do

Product Design & Development

Do you have an idea for a product you would like to see designed and developed for manufacturing? Great! Northwest Plastics works with clients to bring their product ideas to life every day. Maybe your design could benefit from minor tweaks that would result in a product that is easier to manufacture, or your idea is still in its infancy? Either way, we can help! Whether you have a design that needs to be tweaked or have a concept that needs to be designed and brought to life, our design and development team can assist you with every step.

Mold Prep, Or "Tooling Construction"

The next step in product design and development is to build a mold, or “Tooling” as we call it in the industry. Without the proper guidance in this step you can find yourself feeling overwhelmed really quickly. Our team works with you to identify the most efficient and cost effective tooling option. We source and project manage fabricated, machined or cast tooling from local and international suppliers. We leverage our longstanding relationships with quality tool makers on your behalf. We will help you specify requirements, choose the right contractor to supply tooling, review bids with you, and inspect the final product.

Why Rotational Molding?

The rotational molding process (also known as rotational moulding – depending on which side of the 49th parallel you are on) is remarkably simple, as most profound things are. Pigmented plastic beads are added to a mold or form, which is then heated in one of our ovens. The plastic part is formed as the beads melt and fill each of the hollows in the mold as it rotates in a seemingly random (but actually very specific) pattern. The mold is cooled, and the plastic part is removed. Great for short lead times, low tooling costs and complex yet consistent part production.

Is Rotational Molding Right For You?

Manual and CNC Trimming

We finish and trim plastic parts using our 5-axis CNC machine. Having a 5-axis CNC machine means it has the ability to trim complicated shapes without having to do multiple part setups as it has the ability to move on five different axes at the same time. This helps the cutting tool approach the part from all directions resulting in almost limitless applications possible. It also means the parts can be produced quickly and efficiently while maintaining accuracy. A process that can be endlessly repeated. A process that can accurately scale with the quality and manufacturing demands of your business. What does this mean for you? If it can be done, we can do it.

Custom Assembly & Testing

Having over 40 years experience means we have pretty much seen it all. No matter the material, size, timing needs or stringency of quality control; we do it all. Some parts need to be one-piece, others multiple pieces that fit together. Some need to be shipped in individual parts, others assembled. Some need to be simple, others very complex. Some even require complex design inclusions such as metal inserts, graphics, or even foam in the wall of the part. No matter what you need, our response is pretty much always the same: “absolutely, we can do that!”

Floating Great Ideas

Our process is profoundly simple; so what makes Northwest Plastics unique? What makes us stand head and shoulders above the crowd? Our ability to handle EPS foam processing is one of the things that does. We realized that there was a need to make massive things float. So we thought of an innovative way to make that happen! We custom designed, built, tested, and implemented a one-of-a-kind Boiler and Pre-Expander system, that has since become tried and tested. What does this mean for you? Simple: if we don’t already have a solution for your business challenges, we’ll build one!

Shipping and Storage

We are conveniently located on the Canada – US Border in BC, Canada. Every day we ship finished products locally, and around the world, and everywhere in between. What about in between production runs? We store and maintain our client’s Forms and Tooling. In fact, we’ve built our entire facility around ensuring we can continue doing so! Many other rotomolding companies charge for this, or expect their OEM Partners to arrange their own removal, storage, and maintenance of Forms and Tooling. It’s just a part of what we do!

Why Product Developers Choose Northwest Plastic

40 Years Of Successful Partnerships and Counting

For 40 years Northwest Plastics has built lasting relationships with our Product Partners. In fact, in that time not a single one of them has left. Why? For some, it’s because we co-developed new products together. For others, it’s because we helped them fine tune their product through our meticulous 3D CAD review. For others still, it’s because we helped them save during startup with low cost, durable tooling while preparing them with a market ready strategy. But for most, it’s our “standard” worry-free approach of being able to leave the entire process in our hands. How can we help your business?
