Our parts have gone into
Whether you are launching your first product or running a long-established line, the goal is the same: parts that are right the first time, at a price that leaves you room.
We help you turn a 3D-printed model into a part that can be molded at a sensible cost, then get you to samples you can show customers and investors.
A hardware startup sends 3D files for a housing with snap fits and a soft-touch button. We suggest material and wall changes that make it moldable, build the mold, ship samples for a fit check, then deliver the first units assembled and boxed.
Example timeline. Real timing depends on the part, the mold and the shipping route.
For brands selling online or in stores that want steadier quality, a lower unit cost or new sizes and colors added to a line.
A housewares brand wants to extend its best-selling containers. We match the existing look and lids, adjust the design to bring the unit cost down, and ship cartons labeled for Amazon fulfillment centers.
Example timeline. Real timing depends on the part, the mold and the shipping route.
For equipment makers and established manufacturers who buy molded parts and sub-assemblies to drawing, often over many years.
An equipment maker needs a molded service cover, two rubber seals and the brackets that hold them. We supply all of it as one kit per machine, inspected and packed, on a monthly schedule.
Example timeline. Real timing depends on the part, the mold and the shipping route.
For distributors and retailers building a private-label range, from an existing design or one adapted to your market.
A distributor of cleaning supplies wants its own buckets and caddies in brand colors. We adapt existing designs, mold the logo into each part and pack them shelf-ready, shipped in one mixed container.
Example timeline. Real timing depends on the part, the mold and the shipping route.
Two examples of work we have carried from first tooling through long production runs.
Large, heavily ribbed injection-molded plates for the collapsible carts that warehouse robots move through Amazon's logistics operations. We supplied them in volume across the life of the program.
Each square is 10,000 sets.
Developed with the customer around 2010, these frames and related seat components went into seating on Boeing and Bombardier aircraft. Orders continued for more than six years.
Your project contact is based in Canada and works on Eastern Time. Production runs in Zhejiang, one of China's main centers for mold making and plastics. You get answers in English during your business day, and the production team can pick up the work while you sleep.
China is 12 hours ahead of Eastern Time. A question sent at the end of your day reaches the production team at the start of theirs.
Molds are machined and fitted at our tooling partners, then run on automated injection molding lines with robot take-out. Filmed at the toolrooms and molding plants in our production network.
