| Stainless steel | SUS303 / SUS304 / SUS316 / SUS410 | Corrosion resistant parts, medical and food equipment |
| Carbon steel / iron | A3 / 45# / 1215 / 12L14 | General structural parts, shafts and connectors |
| Alloy steel | As specified by customer | High strength and wear resistant parts |
| Brass | H59 / H62 / C3604 | Conductive parts, connectors, valve fittings |
| Copper / red copper | As specified by customer | Electrical and thermal conductive parts |
| Aluminium | 6061 / 6063 / 7075 | Lightweight structures, housings, heat sinks |
| Other materials | Selected on request | Engineering plastics and others by agreement |

Plating
- Zinc plating
- Nickel plating
- Chrome plating
- Copper plating
- Black zinc plating
Anodising
- Natural anodising
- Black anodising
- Colour anodising
Other finishes
- Black oxide
- Polishing
- Brushing
- Sandblasting
- Passivation
- Heat treatment
- Anti-rust treatment
- Cleaning and degreasing
EQUIPMENT
Equipment list
A mix of precision machining equipment covering primary machining, automation and secondary operations, so a part can be completed in one flow.

| Turn-mill centre | Live tool turret | Complex parts with milling, drilling and tapping features |
| Automatic lathe | Multi-station automatic lathe | High volume small hardware and screws |
| Bar feeder | Automatic feeding unit | Higher throughput and stability in batch production |
| Secondary equipment | Screw machine / drilling / tapping | Drilling, tapping, grooving, chamfering, deburring |
INSPECTION
Inspection equipment
To hold dimensional accuracy and batch stability, we keep a range of standard measuring tools and gauges on the floor.
- Vernier caliper
- Micrometer / outside micrometer
- Inside measuring tools
- Height gauge
- Thread gauge
- Plug gauge / ring gauge
- Pin gauge
- Dial indicator
- Profile projector
- Concentricity tester
- Surface and visual inspection tools
- Salt spray test support
QUALITY CONTROL
Quality control process
We work to a simple principle: quality first, delivery you can plan around. Our QC flow covers incoming material, in-process control and final inspection.
- 1
Incoming material inspection
Check material specification, grade and appearance against production requirements.
- 2
First article inspection
A first piece is made and checked for critical dimensions, threads and appearance before the batch runs.
- 3
In-process patrol
Sampling at each operation, focusing on dimensional stability, accuracy and surface quality.
- 4
Final inspection
Check critical dimensions, appearance, burrs, threads and assembly fit after machining.
- 5
Post-treatment inspection
Where plating, anodising or black oxide is required, re-check appearance and function afterwards.
- 6
Pre-shipment inspection
Sampling or full inspection before dispatch, confirming quantity, packing, protection and labelling.
- 7
Packing and dispatch check
Rust protection, impact protection and anti-mixing packing suited to the part, so it arrives safely.
- Produced strictly to drawing and sample
- Critical dimensions under focused control
- First article approval before batch production
- Sampling or full inspection before shipment
- Non-conforming parts isolated immediately
- Traceable production process
