Mold making
Aria connects tool design, in-house mold manufacture, trials and injection molding in one project discussion.

Make the tool decision around the parts you need
The right mold is the one that supports your part, resin and expected demand. Aria reviews those requirements before machining the tool, including the features that affect appearance, release and assembly. You can discuss prototype tooling and repeat-production needs with the team that handles the mold and the molded parts.
Our own facility carries out core mold-making and injection molding work. Trials and sample review connect the tool design to the actual part you receive. If the design changes, we review its effect on the tool, price and schedule before production continues.
Capabilities
Confirm the required production volume and tool design.
Injection tool development
Tool design establishes cavity geometry, resin entry, cooling and ejection. The intended resin, annual demand and part revisions guide the choice of tooling approach.
Core, cavity and release design
Core and cavity geometry define the molded shape. Cooling, venting and ejection must work with the parting line and any side actions so the part can be formed and removed.
Production tooling
Cavity count, cooling, tool material and maintenance access are planned around expected demand. A production tool must support repeatable molding of the selected resin and part geometry.
Typical tooling life
| Parameter | Range | Conditions |
|---|---|---|
| Rapid tooling shot life | Typically 5,000–10,000 shots | Planning range; resin, tool design and maintenance affect life. This is not a warranty. |
| Production tooling shot life | Typically 50,000–1,000,000+ shots | Confirm the required production volume and tool design. |
Planning your mold making order
- Tool materials
Aluminum and steel.
- Tool class
Class 101–105; confirm the class and tool specification for the project.
- Keeping or transferring your mold
Molds remain at Aria after production and can be shipped to the customer on request. The customer pays packing and transport; Aria assists with checking compatibility with the customer’s equipment.
Manufacturing process
Review the part drawing
Confirm the geometry, dimensions and requirements for the part to be molded.
Review moldability
Review the part design for features that affect tooling and repeatable molding.
Select the tool material
Choose tool steel or aluminum to suit the resin, expected production and project requirements.
Machine the core and cavity
Manufacture the mold features to the approved tool design.
Finish the mold surfaces
Prepare the cavity surfaces for the required part appearance and release.
Assemble the mold
Fit the core, cavity, inserts and cooling components into the mold base.
Run trials and check samples
Test the assembled mold and check the sample dimensions and function.
Prepare for production
Monitor the mold during production to maintain the agreed part quality.
Design considerations
Cooling design
Uneven cooling can contribute to distortion and longer cycles. Tool cooling should follow the part geometry and the thermal behavior of the selected resin.
Dimensional acceptance
Identify the fits and dimensions that control assembly. Tool accuracy, resin shrinkage and process behavior all contribute to the dimensions of the molded part.
Gate placement
The gate influences resin flow and leaves a vestige on the part. Review its position against visible surfaces, functional areas and the expected flow path.
Improving moldability
Review thick sections, draft and undercuts while the tool is still in design. A geometry change at this stage can be simpler than modifying finished tooling.
Molding cycle
Filling, packing, cooling and ejection contribute to cycle time. Thick sections and difficult release geometry can affect how quickly the cycle repeats.
Part files and design changes
Provide the current model and drawing together, with the resin, finish, critical dimensions and revision clearly identified. Approve the files used for tool manufacture. If the part changes later, review the effect on the cavity and sampling plan before modifying the tool.
Part size and tool layout
Part size affects cavity layout, tool envelope and handling. Include the complete geometry and the required cavity arrangement in the tooling review.
Preparing the mold brief
Provide the final part model, resin grade, expected quantities and sample acceptance criteria. Identify visible faces and mating features before reviewing gate, parting-line and ejector locations.
Production demand
Expected demand helps determine cavity count and tooling duty. Include forecast repeat quantities as well as the initial sample requirement.
Tool complexity and cost
Undercuts, side actions and difficult cosmetic requirements add tool work. Review whether each feature is needed before finalizing the tool layout.
Tool steel requirements
The resin, fillers, corrosion exposure and production duty influence tool steel selection. Specify the intended molded material before comparing tool grades.
Tooling and part quantity
Compare initial tooling cost with the number of required parts and repeat demand. Additional cavities affect tooling investment as well as output per cycle.
Tooling and production planning
Review tooling, molded-part demand and any assembly or finishing steps together. This makes the initial tool investment and recurring operations visible in the project plan.
Walls, ribs and release
Gradual wall transitions and appropriately designed ribs can reduce heavy sections. Draft and undercuts determine how the part releases from the tool.
Frequently asked questions
What is a mold?+
A mold is a form used to shape and form plastic products. It consists of two halves, the cavity (where the product will be shaped) and the core (which supports the part during production). Molds are typically made from stainless steel or aluminum.
What is your delivery time of mold?+
Usually, the mold delivery time is 3-4 weeks, depending on the degree of mold reproduction. Get Your Free Quote About Plastic Injection Molding Mold Today. With instant injection molding quote online. Get a Injection Tooling Quotes All information and uploads are secure and confidential.
