Part production & in-house mold manufacture
Custom gas assist molded parts, manufactured in our own factory. Connect your part requirements, mold development and production in one clearly defined project.
In internal gas assist injection molding, pressurized gas forms hollow sections within selected regions of a molded plastic part. In a suitable design, it can help address thick sections, weight and appearance requirements.
Our own factory carries out gas assist injection molding and mold manufacture. We start with the part you need, then define the tooling and production scope.
Are you working through these challenges?
Custom part production in our own factory, built around the agreed material, geometry and acceptance requirements.
Define the production brief:
Tooling development with mold manufacture in-house. Consider the plastic flow, gas path and part requirements together.
Define the tooling brief:
Both processes form plastic in a mold. The difference is how selected thicker sections are managed.
Neither route is automatically better. Geometry, material, surface requirements and validation determine the appropriate approach. Read the process guide →
Evaluate the details that determine whether gas assist is right for your part.
Check the gas path, openings and remaining wall against the part’s function.
Plan plastic flow and gas entry together, with mold manufacture in-house.
Use suitable sample evidence to assess hidden features, not only the outside surface.
Specify the grade and the performance you need. Material suitability must be assessed with the part geometry and intended process.
Share the exact resin grade, supplier information and relevant datasheet.
Describe the service conditions before comparing material options.
These are design considerations, not a customer portfolio or a promise that every part is suitable.
Review whether the intended gas path can follow the geometry while leaving the required wall.
Define loads, contact surfaces, mounting points and regions that must remain solid.
Evaluate how branches and transitions affect flow, gas penetration and functional interfaces.
Identify visible faces and acceptable marks before setting the process and tooling brief.
Start with the information you have. Build the next decision around the requirements that matter.
Share the available model or drawing, intended use and design flexibility. Identify what gas assist needs to achieve.
Mark the cosmetic surfaces and provide photographs of the current result, including the areas that need improvement.
Identify interfaces, load paths, mounting points and dimensions that cannot change.
Bring part geometry, material requirements and expected volume together before agreeing the tooling scope.
Share the current part, tool information and desired outcome. Conversion needs an individual review, not simply an added gas inlet.
Gas assist injection molding production is carried out in our own factory.
Mold manufacture is also completed in our own factory, alongside the agreed development scope.
Begin with function, surfaces and dimensions rather than assuming a process will suit every geometry.
Make the drawings, resin information, quantities and tooling deliverables clear before quotation.
Define the sample evidence, critical checks and approval requirements before accepting the result.
Benefits depend on the part, material and validated process. They are not guaranteed savings.
A hollowed section can use less material than an equivalent solid section, where the required function is retained.
Gas pressure can help address sink in appropriate thicker regions, subject to geometry and process validation.
Evaluate hollow sections alongside solid bosses, mounting features and the part’s assembly requirements.
Use the project brief and sample evidence to assess trade-offs before committing the final production scope.
Send your drawing, material requirements, expected quantity and target schedule. We’ll use them to define the next step.
