Meta Description

Discover the key differences between custom (small batch) machining and mass production machining. YuXiang Parts provides high-quality CNC machined components such as oil pans, brackets, and transmission parts for both prototype and large-scale manufacturing.

1. Introduction

In the precision manufacturing industry, machining requirements vary widely depending on quantity and project goals.
Generally, machining can be divided into two main categories:

Custom (Small Batch) Machining

Mass Production Machining

Both serve unique purposes and are essential in modern manufacturing. Understanding their differences can help you choose the best production method for your project.

2. What Is Custom (Small Batch) Machining?

Custom machiningfocuses on producing single pieces or small batches of precision components.
It is ideal forprototypes, R&D projects, or customized partsthat require quick turnaround and design flexibility.

✅ Key Features:

Flexible order sizes — even one piece can be produced

Quick programming and setup changes

Experienced machinists capable of complex adjustments

Higher unit cost due to setup time and tooling changes

Perfect for prototyping, sample development, and short-run production

��Typical Products:

Custombrackets

Oil panprototypes or limited batches

Transmission housings, test fixtures, or non-standard parts

3. What Is Mass Production Machining?

Mass production machiningis used for large-volume, repeatable parts.
It focuses onefficiency, consistency, and cost optimization, making it ideal for long-term supply and OEM projects.

✅ Key Features:

Standardized processes and tooling

Lower unit cost due to scale efficiency

High repeatability and stable quality

Suited for annual or continuous supply projects

Often certified underIATF 16949

⚙️ Typical Products:

Oil pansfor automotive transmissions

Transmission bracketsand support housings

Shafts, covers, and precision machined housings
