What is Tooling & Production?
Tooling refers to the custom-made molds, dies, or forms used in manufacturing processes to shape raw materials into finished parts. Tooling is the “negative” of the part, a cavity or form that gives the material its final shape when it is injected, poured, or pressed.
In a word: Tooling is the specialized equipment that determines the exact shape, features, and precision of every part produced.
Production refers to after complete building the tooling (molds, dies, or fixtures) and then using that tooling to produce finished parts in volume. Tooling creates the “shape maker”, production uses it to make thousands or millions of identical parts.
What’s advantages of Tooling & Production?
Consistent Quality & High Repeatability
Tooling produces identical parts every cycle， part #1 and part #1,000,000 are nearly the same. This minimizes scrap, reduces rejects, and ensures reliable quality for high-volume production.
Very High Production Speed
Tooling enables extremely fast cycle times: injection molding in seconds, Without tooling, each part would take hours (machining, manual fabrication).
Low Cost when High Volume
High upfront tooling cost is spread across tens of thousands to millions of parts. The more you produce, the cheaper each part becomes pennies at very high volume.
Minimal Material Waste
Tooling-based processes (injection molding, die casting, stamping) achieve 85–99% material utilization, far better than CNC machining. Less scrap means lower material cost plus better sustainability.
Complex Geometries & Fine Details
Tooling produces intricate shapes, thin walls, undercuts, threads, and surface textures that would be impossible or extremely expensive to machine individually. All features are built into the mold or die.
Automated Operation & Wide Material Range
It works seamlessly with robotic part handling and inspection systems, reducing labor costs and enabling lights-out manufacturing. Material versatility, works with both plastic and metal, even composite materials.

FAQs About Our Tooling & Production Services
Why Tooling?
Tooling is the foundation of high-volume, repeatable manufacturing. Tooling turns a slow, manual process into a fast, automated, high-volume production system. If you need mass production, you must be choose tooling and molding production.
What kind of equipment do you use?
The molding workshop includes EDM, wire EDM, 50+CNC machining center, 50+injection machines ranging from 80 to 1000 tons, ect to meet different production requirements. Request equipment list, contact our team: ashely@rpdmfg.com.
Do you support export mold or production?
Yes, exactly. We support both. You can either for use at your own facility or leave it with us for long-term molding production.
What is your quality control system?
We operate under a rigorous Quality Management System (QMS) aligned with ISO standards. Our 5 Steps QC process is including IQC (Incoming Quality Control) , FQC (Final Quality Control) , OQC (Outgoing Quality Control) for routine production.
QE (Quality Engineering) / CAPA (Corrective and Preventive Actions) implemented throughout the entire product lifecycle, especially during the post-sale stage, to drive continuous improvement. Simply speaking 100% inspection before shipment to ensure zero defects.
What kind of quality assurance or warranty do you offer on orders?
One of the reasons engineers purchase from RPD is that we take on all the risks for you. We guarantee you’ll love what you get. Not happy with it? We’ll either redo it or give you a full refund. Your purchase is completely risk-free.
Why tooling is so expensive?
Material – Hardened steel (costly but durable for high volume)
Complexity – CNC, EDM, polishing; multi-cavity, undercuts add cost
Precision – Tight tolerances require advanced equipment & skilled labor
Customization – Every mold is custom-built for a specific part
Engineering – Significant design time for cooling, ejection, and geometry
Which kind of file formats can I send for tooling& production?
We accept STEP, IGES, STL, DWG, DXF, and other common CAD formats.
What Factors will Influence Tooling Design?
1. Part Geometry – Shape, size, and complexity drive mold design. Thin walls, intricate details, and complex geometries require specialized features like additional cooling or advanced gating systems.
2. Material Selection – The plastic type affects cooling rates, shrinkage, and flow. Polypropylene shrinks more; polycarbonate needs higher mold temperatures. Abrasive or corrosive plastics also demand wear-resistant mold materials.
3. Tolerances & Precision – High-precision parts (automotive, medical) require tighter mold tolerances — which complicates design and increases cost.
4. Ejection System – Ejector pins, air blasts, or stripper plates must be carefully integrated to remove parts without damage — affecting both design and cycle time.
5. Gate Design – Gate type and location (direct, pin, edge) control how molten plastic enters the mold, impacting part quality, surface finish, and cycle time.
6. Undercuts & Parting Lines – Undercuts or complex shapes may require side actions or lifters to release the part, increasing mold complexity and cost.
Can we store the mold at your facility for future production orders? Do you provide free maintenance for the mold?
Yes, we offer two key benefits for molds set up at our facility: free storage and free maintenance.
