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

FAQ

1. Are you a manufacturer or a trading company?

We are a factory located in  China, with 20 years of rich experience,
covering 6000 square meters. Complete facilities, including 3D quality inspection equipment, ERP system and 40 machines. If necessary, we can provide you with material certificates, sample quality inspection and other reports.

 

2. How to get a quote?
Detailed drawings (PDF/STEP/IGS/DWG...), including quality, delivery date, materials, quality, quantity, surface treatment and other information.

 

3. Can I get a quotation without drawings?

Can your engineering team draw for my creativity? Of course, we are also glad to receive your samples, pictures or detailed size drafts for accurate quotation.

 

4. Can you provide samples before mass production?

Of course, the sample fee is necessary. If possible, it will be returned during mass production.

 

5. What is the delivery date?

Generally, the sample lasts for 1-2 weeks and the batch production lasts for 3-4 weeks.

 

6. How do you control quality?

(1) Material Inspection - Check material surfaces and approximate dimensions.

(2) First inspection of production - ensure

critical dimensions in mass production.

(3) Sampling inspection - check the quality before delivery to the warehouse.

(4) Preshipment inspection - 100% inspection by QC assistant before shipment.

 

7. After sales service team

If you have any problems after receiving the product, you can provide feedback through voice call, video conference, email, etc. within one month. Our team will provide you with solutions within a week.
