Product Description

Medical Mold Rod CNC Milling Drilling and Tapping

Product Description

Product Application:
These are high-precision, custom-machined pins, rods, and core components used in the manufacturing and forming processes of medical devices and pharmaceutical products.

Injection & Blow Molding: Core pins, ejector pins, and cavity inserts for molding plastic medical components (syringe barrels, IV connectors, inhaler parts).
Extrusion & Tubing Manufacturing: Mandrels and tip formers for shaping silicone, PTFE, or polymer tubing used in catheters, drains, and fluid lines.
Assembly & Calibration Fixtures: Precision alignment pins, guide rods, and tooling shafts for automated assembly lines or quality control jigs for medical devices.
Pharmaceutical Tooling: Punches and dies for tablet presses, or forming tools for drug-delivery patches.
 
Product Description:
We provide precision CNC machining services for medical-grade mold pins, mandrels, and tooling rods. These are not end-use medical devices, but critical production tooling components that directly influence the quality, consistency, and geometry of final medical products. Starting from hardened tool steels, stainless steels, or other durable alloys, we perform CNC milling to create complex profiles and flats, precision drilling for cooling channels or ejector holes, and tapping for assembly threads. The dimensional accuracy, surface finish, and durability of these components are paramount, as they must withstand thousands of cycles in production while maintaining exact tolerances. We specialize in producing these wear-resistant, long-life tooling elements to customer specifications, supporting the high-volume manufacture of reliable medical products.

Main Product

Base Material	Common Materials	Tool Steels:H13, P20, S7, 420 Stainless (hardened).Stainless Steels:304, 316, 17-4PH.Others:Aluminum (for prototypes/fixtures).
	Hardness (if applicable)	Tool steels typically hardened to48-52 HRCor higher for wear resistance.
Machining Processes	Primary Services	CNC Milling:For contours, profiles, flats, and complex 3D shapes. Precision Drilling:Deep holes, micro-holes, angled holes for cooling/venting. Tapping:Internal threads (metric, unified) for assembly and mounting.
	Additional Processes	CNC Turning(for round profiles),Grinding(for ultra-fine finish/tolerance),Heat Treating,Surface Coatings(e.g., TiN, CrN for extra wear resistance).
Design & Geometry	Component Types	Core pins, ejector pins, leader pins, mandrels, forming punches, insert blanks.
	Typical Features	Tapers, steps, undercuts, flats (wrench flats), grooves (for o-rings), threaded ends.
Dimensions & Tolerances	Diameter Range	1 mm to 100 mm(standard machining range).
	Length Range	5 mm to 500 mm(subject to diameter and rigidity).
	Standard Machining Tolerance	±0.0125 mm (±0.0005")on critical dimensions.
	High-Precision Tolerance	±0.005 mm (±0.0002")achievable with grinding.
	Hole/Thread Positional Tolerance	Typically within0.02 mmtrue position.
Surface & Finish	Surface Finish (As-Machined)	Ra 0.4 - 0.8 µm (16 - 32 µin)standard.
	Polished Finish	Mirror polish (Ra < 0.1 µm / 4 µin)available for mold surfaces to impart smoothness on final plastic parts.
	Texture/EDM Finish	Specific EDM textures can be applied per customer request.
Quality & Compliance	Inspection	Full dimensional inspection via CMM. Hardness testing for heat-treated parts.
	Documentation	Material certification, heat treat certificate (if applicable), and inspection report provided.
	Application Standard	Components are machined to be compatible with standard mold bases (e.g., DME, HASCO, MISUMI) or per custom prints.
	Production Environment	While not medical devices themselves, they are often produced under a controlledISO 9001quality system.
