What Is Rapid Tooling?
Rapid Tooling is a mold manufacturing method designed to significantly shorten mold development cycles. Compared to traditional mass-production molds, which often have lead times of 6–12 weeks, Rapid Tooling typically completes mold manufacturing and delivers the first batch of injection-molded samples within 1–3 weeks.
This does not mean compromising on quality; rather, by optimizing mold structure design and selecting appropriate mold materials (such as aluminum alloy or pre-hardened steel), it significantly reduces development time and upfront costs while still meeting product validation requirements.
For teams that need to conduct functional validation, visual confirmation, or small-batch market testing before full-scale production, Rapid Tooling is the most efficient path forward.

Manufacturing Capabilities
Dimud operates three in-house manufacturing facilities and has full in-house mold-making capabilities, eliminating the need to outsource any core manufacturing processes:
High-Speed CNC Machining
High-speed 5-axis milling, suitable for high-precision machining of aluminum and steel mold cavities, with a surface roughness as low as Ra 0.4 μm
EDM (Electrical Discharge Machining)
Precision EDM processing of complex, irregular cavities, deep ribs, and fine text, ensuring a level of precision and detail reproduction that conventional machining cannot achieve.
Wire Electrical Discharge Machining (WEDM)
Used for high-precision contour machining of inserts, sliders, and precision-fit components, ensuring the fitting accuracy of all functional parts in the mold
CMM (Coordinate Measuring Machine) Inspection
Once the mold is completed, a CMM is used to perform a full inspection of critical dimensions, and a formal dimensional report is issued to ensure the traceability of the mold delivery data.
How It Works — From File to First Parts
A streamlined 6-step process designed to eliminate uncertainty and keep your project on schedule.
Step 01 — Upload Your Design
Submit your CAD files (STEP, IGES, STP, or STL formats are supported) and provide basic requirements, including the target material, estimated quantity, and delivery schedule.
Step 02 — DFM Review & Quotation
The engineering team conducts a Design for Manufacturability (DFM) analysis of the design documents to identify potential wall thickness issues, insufficient draft angles, or structural risks, and provides a quotation at the same time.
Step 03 — Mold Design & Confirmation
Based on the approved design, proceed with the mold structure design, including parting line planning, gate placement, and cooling system layout. Once completed, submit the design to the client for review and approval.
Step 04 — Tooling Fabrication
Once the mold enters the machining phase, the core and frame are manufactured using CNC precision milling, EDM (electrical discharge machining), and high-precision grinding processes. A dedicated engineer monitors progress throughout the entire process.
Step 05 — T1 Sampling & Approval
The initial mold trial has been completed, and the T1 prototype has been delivered, accompanied by the First Article Inspection (FAI) report and critical dimensional measurement data. Production will commence only after the customer’s approval.
Step 06 — Production & Delivery
We proceed with formal injection molding production in accordance with the confirmed process parameters. After passing visual and dimensional inspections, the products are packaged, shipped via international logistics, and tracked throughout the entire process.

Why Choose Dimud for Rapid Tooling?
Not just fast — engineered right the first time.
We are not middlemen; we are manufacturers
With our in-house mold shop at the core of our operations, Dimud handles all Rapid Tooling projects—from mold design to injection molding—entirely in-house. There is no outsourcing, no communication gaps, and we take direct responsibility for both delivery times and quality.
First-Shot Accuracy, Fewer Iterations
Before launching any Rapid Tooling project, we conduct a mandatory DFM (Design for Manufacturability) review to identify issues such as uneven wall thickness, insufficient draft angles, and the risk of shrinkage early on. This helps minimize the likelihood of rework during trial molding from the outset, saving you time and money.
Steel or Aluminum — You Decide, We Deliver
We have the capability to develop both aluminum alloy rapid-prototyping molds and P20/H13 steel molds. We use aluminum molds for prototype validation to control costs and lead times, and switch to steel molds for small-batch production to ensure both mold longevity and part consistency. We are a one-stop supplier covering all your mold needs from validation through to pre-mass production.
Fast turnaround without compromising accuracy
Dimud’s Rapid Tooling projects maintain standard tolerances within ±0.05 mm, with critical mating surfaces achieving tolerances as tight as ±0.02 mm. Upon completion of each mold, a CMM (Coordinate Measuring Machine) report is issued, ensuring data traceability and verifiable precision.
What You Need to Know About Custom Parts Manufacturing
Choose 3D printing if you need to validate a design concept; choose Rapid Tooling if you need to test the performance of actual materials, check assembly fit, or submit samples for customer certification and regulatory review—the test results for injection-molded parts are closer to those of the final production parts.
Aluminum molds are suitable for small-batch production of up to 50,000 cycles but are not suitable for long-term, high-volume mass production. When transitioning to mass production, Dimud can directly upgrade the mold to a steel mass-production mold on the same platform without the need to resubmit design files.
To initiate a quote and DFM review, please provide 3D CAD files in STEP or IGES format, along with 2D engineering drawings (PDF) that specify critical tolerances and material specifications.
Aluminum alloy rapid tooling starts at approximately $800, while P20 steel Bridge Tooling typically ranges from $2,000 to $8,000. You will receive an accurate quote within 24 hours of submitting your drawings.
