Necessary Works

Raw materials (Ingredients)
Raw materials (Ingredients)
Mixing materials according to customer needs.
1
Forming
Forming
Forming goods according to demand and conducting a rigorous review.
2
Sintering
Sintering
Under the protection of nitrogen hydrogen (NH3) gas, the temperature is 800 ° (bronze) ~ 1150 ° (stainless steel) sintering, the sintering time is about 4HR (depending on the workpiece material).

Selectivity Engineering

Integral
Integral
Function: Increase accuracy (including external dimensions, true degree, etc.) with a minimum accuracy of 0.005mm.
1
Vapor Treatment (Blackening)
Vapor Treatment (Blackening)
Function:
1. The appearance of the workpiece is black.
2. Increase the surface hardness of about HRB20°
3. Increase the rust prevention capacity (about 20HR for salt water test)
4. Match with the component color.
5. Use pure water distillation No harmful substances.
2
Vibration Grinding
Vibration Grinding
Type 1:
The types of vibrating beads are divided into
*Beadless vibration
*Ball vibration(ψ1.0~ψ3.0mm)
*UFO bead vibration
*Sponge stone vibration
Type 2:
The type of vibration interface is divided into
*Dry vibration (forbidden oil)
*Water vibration (stainless steel)
◎Oil vibration (general)
3
Grouping
Grouping
According to the requirements of the client, more than two workpieces (powder parts + non-powder parts) are combined to control the quality of the pipe, which is convenient for customers to use, reduce customer material management and increase service diversity.
4
Raw Edge Brushing
Raw Edge Brushing
Through the special brush design, the sharp angle and the burr of the workpiece's clamping line are removed.
5
Copper Infiltration
Copper Infiltration
A piece of copper is infiltrated into the iron or alloy steel workpiece. To increase strength and density.
6
Oily Treatment
Oily Treatment
Using the vacuum principle, the air in the capillary pores of the workpiece is evacuated in an atmosphere pressure of -72 mmHG, and the customer-specified oil (viscosity index 30-80) is injected.
7
Rust treatment
Rust treatment
The appearance of the workpiece is subjected to mucosal rust prevention (viscosity index 5-15). Salt water test over 24hr, over 180 days in normal temperature climate.
