0.03mm Micro Hole OEM Custom Stainless Steel runner Plate Fast Delivery
Product Overview
Xinhsen Technology is a leading manufacturer of high-precision etched runner plates used in injection molding, die casting, and industrial fluid distribution systems. Our chemically etched runner plates ensure ultra-smooth material flow, minimal pressure loss, and extended tooling life compared to conventional machined alternatives.
These critical components are widely used in:
✔ Plastic injection molding (hot runner & cold runner systems)
✔ Die casting (aluminum, zinc, magnesium alloys)
✔ Industrial fluid control (coolant distribution, lubrication systems)
✔ Semiconductor & PCB manufacturing (chemical etching process plates)
With 20+ years of metal etching expertise, we deliver custom-designed runner plates with micron-level accuracy, helping manufacturers improve production efficiency and reduce waste.
Key Features & Benefits
1. Ultra-Precise Flow Channels
Channel width: As fine as 0.02mm
Surface roughness (Ra): <0.2μm (smoother than CNC machining)
Tolerance: ±0.03mm (standard), ±0.01mm (high-precision)
2. Optimized Material Flow
Tapered & radiused channels prevent material stagnation
Balanced runner systems ensure even filling of multi-cavity molds
No burrs or micro-cracks (unlike laser-cut alternatives)
3. Superior Material Selection
Stainless Steel (SS304, SS316L, 420J2) – High wear resistance
Tool Steel (H13, P20, S7) – For high-pressure applications
Copper Alloys (C11000, C17200) – Excellent thermal conductivity
Titanium (Gr1, Gr5) – Corrosion-resistant for harsh environments
4. Enhanced Durability & Performance
Hardened options available (HRC 45-60)
Plating services (Ni-PTFE, CrN, DLC) for reduced friction
Integrated cooling channels for thermal management
5. Cost-Effective Manufacturing
No expensive tooling required (ideal for prototype molds)
Faster lead times (5-7 days for prototypes)
Scalable production (up to 10,000+ units/month)

FAQ
Q1: What's the advantage of etched runner plates over machined ones?
A: Etched plates provide smoother channels, no burrs, and better wear resistance at lower cost for complex designs.
Q2: Can you produce conformal cooling channels?
A: Yes! We specialize in 3D cooling channels that follow mold contours for optimal thermal management.
Q3: What's your lead time for prototype runner plates?
A: 5-7 working days after design approval (faster than CNC machining).
Q4: Do you provide hardening/coating services?
A: Yes – We offer nitriding, DLC coating, Ni-PTFE plating for extended service life.
Q5: How small can you make the runners?
A: We routinely produce 0.02mm micro-runners for precision applications.
