2. Small Batch vs Mass Production: How Our Factory Handles Orders
Small Batch Custom Production
For small orders, our factory uses high-precision multi-tool CNC lathes . These machines can hold 10–15 tools, enabling:
- Drilling, threading, tapping, turning, and boring in one setup
- Quick tool changes without disassembling
- High flexibility for different sizes and materials
Advantages:
- Ideal for custom orders and complex pipe fittings
- High precision and quality control
- Skilled operators manage programming and tool setup
Challenges:
- Higher cost per unit because of setup time, tool use, and smaller material efficiency
- Requires experienced staff for programming and operation
Mass Production
For large orders, we use cost-effective CNC lathes with 4–6 tools. Each fitting may go through multiple setups, but this allows:
- Stable production with consistent quality
- Lower cost per unit due to bulk material and labor distribution
- Efficient allocation of 1 lead technician and 7–10 operators
Advantages:
- Fast production for standard fittings
- Cost-effective and suitable for long-term contracts
- Reliable quality through repetitive processes
3. Materials and Quality Control in Our Factory
We only use premium steel to produce durable pipe fittings.
- Carbon steel ST37/1020/1035/1045: cost-effective, stable, easy to machine
- Alloy steel 40CR,42CrMo: for high-strength and automotive applications
- Stainless steel 201/ 304/316: for corrosion resistance in industrial and HVAC systems
Our quality process includes:
- Raw material inspection before processing
- CNC machining with precision tolerances
- Thread consistency checks for each fitting
- Surface treatment as per customer request (galvanizing, electroplating, blackening)
- Final inspection before packaging
4. Applications of Our Steel Pipe Fittings
