Passivation
We offer passivation services for the removal of metal oxides; heat-treat scale, and other foreign materials from stainless steel and other metals, leaving the surface chemically clean and prepared for further processing.

Silk Screening
XHX Precision Industry offers color choices in single, dual, triple or multi-color variations and Pantene color requirements. Telecommunications and Commercial Industries use silk screening on boxes, panels and various other parts and products.

Gold Plating
Gold Plating is used for many different electronic and electrical purposes, where the part is designed to operate on complex, high-reliability electronic devices. The majority being applied to three specific types of components: semiconductors, printed/etched circuits, contacts/connectors and high-end decorative items. Industries also use Gold plating for decorative applications.

Silver Plating
Industrial Silver plating provides an economical coating typically used for telecommunication and electrical products. It bestows a surface that can be soldered and exhibits low electrical resistance. The tarnish resistance is equal to that of a good water dip lacquer coating.

lectroless and Electro-Deposited Nickel Plating
These Nickel Plating processes deposit a uniform thickness of Nickel onto products by chemical reduction; this allows even the most complex shaped product to be plated with no edge build-up. Other advantages of Nickel Plating include superior chemical and corrosion resistance, a hard, highly protective, bright, and reflective coating that yields excellent wear. Nickel's low friction and superb conductivity characteristics make it appropriate for Electronic, Tooling, and Commercial Industries.

Shot Blast Finishing
We offer Shot Blasting operations for providing various surface finishes on Cast products. It can produce a cosmetically better-looking product. We offer various size shot for different surface finishes.

Tin Plating
Tin plating is extensively used in Food, Electrical, and Electronic Industries. Because it is safe and nontoxic, Tin is universally utilized in the Food Processing Industry. Plus offers first-rate corrosion resistance and is pliable with low porosity. Also used for Electrical and Electronic, Tin plating has the ability to protect base metals from oxidation, thereby preserving the potential for soldering. 

Zinc and Zincate Plating
XHX Precision Industry offers two types of Zinc plating: Alkaline Zinc exhibits good brightness, ductility, and chromate receptivity, and has reliable and consistent coverage. Chloride Zinc deposits an outstanding brightness and plates difficult substrates such as castings

Metal Sourcing Quality Control & Reliability

1) ISO 9001:2015
We achieved certification to ISO-9001-2015. In this way,we standardized our production process, and made the quality stable, and also reduced the costs.

2) Raw Material Inspection
Incoming raw material were kept in control strictly, because we believe raw material in good quality is the foundation of the high quality of the products.

All the raw materials are bought from the certificated sources stably. Product quality documentations and inspection reports must be provided by the supplier, and random inspection will be implemented during the materials' arrival.

3) Computer Simulation
Simulation programs tools (CAD, Solidworks, PreCast) are used to make the engineering works of casting more predictable to eliminate the defects and improve the stability.

4) Chemical Composition Testing
Chemical composition analysis to the castings is required to ascertain the chemical composition of a heat of steel. Specimen will be taken and tested both pre-pouring and post-pouring to control the chemical composition within the specification, and the results must be doubled checked again by the third inspectors. The specimens being tested also are kept well for two years for tracking using. Heat numbers can be made to keep the traceability of the steel castings. The Spectrometer and Carbon Sulfur analyzer are the main equipment for the chemical composition testing.

5) Non Destructive Testing
The non destructive testing can be processed to check the defects and inner structure of the castings.
- Magnetic Particle Examination
- Ultrasonic Flaw Detection
- X-ray Examination

6)Mechanical Properties Testing
The mechanical properties testing must be done strictly by the professional equipment as in the following:
- Metallographic Microscope
- Hardness test machine
- Tension tester
- Impact strength tester

 7) Dimensional Inspection
Process audit will be implemented during the whole machining process of the metal parts according to the drawings and machining process card. After the parts being machined or finished the surface treatment,three pieces or more pieces according to the requirements will be pick out at random,and dimensional inspection will be implemented.The inspection results are all recorded well,and represented on the paper as well as in the data-base by computer.

Our dimensional inspection can be the one or full of the following method.
- Vernier Caliper of High Precision
- 3D scanning
- Three -coordinates Measuring Machine
