Cost-Effective Zinc-Plated Steel Shaft – Optimized for Mass Production

We are pleased to introduce our carbon steel turned component, manufactured from high-quality 12L14 free-cutting steel. Designed to meet demanding industrial standards, this part delivers excellent performance, durability, and cost efficiency.

It is widely used as a metal shelf support pin, providing reliable structural support and stable load-bearing performance in various applications.

Key Specifications

Material	12L14 steel
Surface Finish	Zinc plated (capable of passing 96-hour salt spray test)
Outer Diameter Tolerance	±0.05 mm
Length Tolerance	±0.2 mm
Construction	Two-piece assembled structure

The Challenge

Initially, this part was designed as a one-piece component. However, due to the large variation in shaft diameter, single-piece machining resulted in:

• Low production efficiency

• High material waste

• Excessive manufacturing costs

This made it difficult to meet the target unit price.

Our Engineered Solution

With nearly 30 years of experience in metal turned parts manufacturing, our engineering team proposed an optimized two-piece assembly solution:

1. Process: Both components are efficiently produced using automatic lathes

2. Assembly: The two precision parts are assembled into the final product

3. Result:

• Significantly improved production efficiency

• Reduced material waste

• Achieved target cost

• Maintained all required tolerances and 96-hour salt spray performance

This solution ensures consistent quality and makes the component highly suitable for applications such as metal shelf support pin, where both cost control and reliability are critical.
