End-to-End 6D Solutions, From Concept to Mass Production. Integrated 5 Steps Quality Control Across Every Stage.
Phase 1: DFM & Material selection
The process encompasses: conducting a product feasibility analysis, specifying the manufacturing processes and mold materials, establishing tolerance standards, and formulating cost optimization strategies.
Phase 2: Mold Design
The scope includes leveraging mold flow analysis, design simulation, and structural optimization to guarantee high performance and superior manufacturability.
Phase 3: Mold Manufacturing
Encompasses precision manufacturing processes, including CNC machining, EDM, texture，assembly, polishing, etc, each executed to exacting standards.
Phase 4: Mold Testing
De-risks production by using in-house trials to verify mold function and confirm part quality.
Phase 5: Sample Confirmation
Before the final approval, provide the customers with satisfactory samples for evaluation and feedback.
Phase 6: Mold & Parts Delivery
Upon customer approval, molds will be either shipped or retained in-house for batch production and free maintenance.

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.
