This project involves the manufacturing of custom engine parts and spindle components for industrial applications.
All parts were produced based on customer drawings, with strict requirements on dimensional accuracy, surface finish and mechanical performance.
We support OEM production based on customer drawings or samples, with full control over casting and machining processes.
Project Information
- Project Type: Engine Parts & Spindle Components
- Manufacturing Process: Casting + CNC Machining
- Material: Alloy Steel
- Application: Industrial Machinery / Mechanical Systems
- Production Type: OEM based on drawings
Manufacturing Process of Engine Parts and Spindle
The components were manufactured through a combination of casting and machining processes.
The process includes:
- Raw casting production for near-net shape
- CNC machining for precision dimensions
- Drilling, threading and finishing
- Surface treatment if required
Precision casting processes like silica sol casting can achieve tolerance levels up to CT4–CT6 with surface roughness around Ra 3.2–6.3 μm, reducing the need for machining.
This combination of casting and machining allows complex parts to be produced efficiently while maintaining high dimensional accuracy and mechanical performance.

Key Challenges in This Project
The main challenges included:
- Maintaining tight tolerances for spindle fitting
- Ensuring concentricity and alignment
- Reducing machining allowance after casting
- Achieving consistent quality in batch production
These challenges were controlled through process optimization and strict inspection.
Spindle components require high precision in concentricity and alignment to ensure stable rotation and performance in mechanical systems.
Importance of Precision in Engine and Spindle Parts
Engine parts and spindle components require high precision and durability, as they directly affect performance and reliability.
Even small deviations in dimension or alignment may lead to:
- Increased wear
- Reduced efficiency
- Assembly issues
