Learn How Our Injection Molding Services Result in Tightly Toleranced Parts

With machine tonnage ranging from 35 tons to 940 tons, Noble Plastics can produce small run prototyping up to large-scale production runs of 1 million+ pieces. Advanced monitoring capabilities on all production cells to include cavity pressure, production, process and asset monitoring, all connected to our proprietary industry 4.0 application, ROC 40™. These systems facilitate advanced molding and quality processes. Robotic automation systems are standard in our facilities for part segregation, inspection, and consistent handling.

Noble Plastics has over 15 years of experience as an ITAR registered supplier with the Department of Defense. A combination of precision molding, available post-mold machining, and consistent automated handling are key when producing tightly toleranced parts.

Our climate-controlled quality lab has advanced metrology tools to include a scanning coordinate measuring machine, portable laser scanner, and precision vision systems, providing the ability to quickly inspect both simple parts and those with very complicated GD&T specifications.

Our engineering team utilizes virtual molding software to manage expectations by simulating the injection molding processes during manufacturing development. This creates predictions of material flow, heat flux, warpage, and allows for troubleshooting of challenges often unforeseen in the molding process.

What things should be provided when coming to us with an idea?

To quote a part, we will request at least a part drawing with tolerances, material specifications, and number of units to produce. Preferably, we can be provided CAD/3D files, samples of parts, a material selection and alternative, quality specifications, and packaging specifications.

What materials do we use? Which ones do we NOT use?

Noble has experience will all common commodity resins but has specific expertise in engineering grade resins with fiberglass and carbon fiber fillers. Noble does not mold PVC.

What are the smallest and biggest size products we make?

Noble can make parts as small as a few grams and a quarter of an inch up to 10+ pounds and 40+ inches.

What are ideal and minimum quantities for injection molding?

There is no universal rule for minimum quantities when considering injection molding. Generally, with tools costing at least $10,000 for the smallest and simplest parts, production volumes of a few dozen parts or even a few hundred parts can rarely carry a proportion of the capital cost of the molds. It is not uncommon for injection molds to cost between $50,000 and $500,000. In this range, it is expected that production volumes would be at 10,000 units and up.

What is the difference between domestic vs overseas tooling?

For a long time, there existed significant differences in quality and costs between domestic components and overseas tooling. Those gaps are narrowing, and while the direct costs of overseas tooling hold an advantage over domestic molds, the risks associated with overseas molds are getting higher: namely the protection of intellectual property, ancillary costs like tariffs and transportation, and global challenges to the supply chain, workforce, and pandemic-affected transfers of materials.
