Miniature Valve Components
For companies that produce quality miniature valves for medical, pharmaceutical, defense or other high tech industries, MW Components is a valued partner for cold headed valve parts, including valve needles, valve pins and stems, and coined valve seats. We are focused on value creation, increased speed to market, reduced cost and improved quality, compared with other contract manufacturers who focus strictly on commodity parts.
Custom Manufacturing
Custom Micro-components
MW can combine secondary processes that many other cold headers do not, for example, roll forming an air valve ball head.
Not only do we perform specialized forming and secondary processes, but we also have access to specialty materials and can create various customizations in non-standard sizes and configurations, making us a leader in micro-component production.

Examples of Custom Solutions
MW produced the part with a very thin wall meeting the flatness specs, while at the same time, actually improved the valve’s surface strength by virtue of work hardening the material property from the cold forming process. Production quantities exceed 4,000,000 parts per year, with no degradation of tooling or part compliance.
Material: Lead-free CDA 260 Brass
Manufacturing Method:
- Cold Heading
- Extrusion
- Upsetting
- DeBurring
- Finishing
Customer Benefits:
- 70% cost reduction
- 5x faster throughput
- 100% net shape, NO material scrap/waste
- Increased tensile strength
- Consistent quality at high tolerances
Advantages:
- Tight tolerances Pressure Regulator Valve Pin
- 100% Net Shape - No Material Scrap
- Significantly lower cost than a machined part
- Work hardening enhances component durability and product life cycle
- Eco-friendly lead-free brass
Material: 304 stainless steel.
Manufacturing Method:
- Multi-Die cold-formed & form rolled.
Notable Features:
- Three diameter-headed pin.
- High surface finish. No machining lines or machining tit present at either end of the part.
- Note the perfectly round shape on the ball head.
Advantages:
- Material waste is minimal.
- Production speeds are high allowing for low production costs. Much faster than machining.
- Concentricity of all diameters is near perfect: TIR approx. .002".
Material: CDA 260 brass (unleaded brass); gold plated.
Manufacturing Method:
- Multi-Die cold-formed on cold heading machine.
Notable Features:
- Six OD diameters present on the pin.
- Rolled undercut pin retention feature.
- Precise chamfers at both ends.
Advantages:
- Material waste is minimal with a cold heading.
- The part is formed from no-lead brass round wire.
- High surface finish.
- No machining lines or machining tit present at either end of the part.
- Normally machined parts are turned from leaded brass material (ie: CDA360). Lead is being discouraged from use worldwide and the CDA 260 (unleaded brass) is a type of brass that is easily cold-headed and will substitute easily.
- Production speeds are high allowing for low production costs. Much faster than machining.
- Concentricity of all diameters is near perfect: TIR approx. .002".
- Rolled undercut provides a locking feature for retention in plastic.
Material: CDA 260 brass (unleaded brass).
Manufacturing Method:
