1. CNC automatic processing

CNC machining usually refers to precision machining controlled by computer. Therefore, it can be controlled by the program instructions of the NC machine tool, and the whole processing process is automatically carried out according to the program instructions. The machine tool has a high degree of automation, which greatly reduces the labor intensity of workers.

2. High CNC machining accuracy

The second advantage of CNC technology is the consistency and accuracy of the workpiece. Today, the typical accuracy of CNC machine tools has reached two thousandths to four inches or 0.05 to 0.10 mm, and the repetition accuracy is close to or better than eight thousandths of inches or 0.02 mm. This means that once the program has been validated, it can easily produce two, ten or a thousand identical parts with the same accuracy and consistency. Mass production can be realized, and the product quality is easy to control.

3. CNC processing flexibility

Since these machines are run by computer programs, running different artifacts is as simple as loading different programs. This also brings another benefit, namely fast conversion. Because these machines are very easy to set up and run, and can easily load programs, their setup time is very short.

4. High CNC processing efficiency

CNC machining can carry out multi coordinate linkage and process complex zero points. When the shape and size of parts need to be changed, only the NC program needs to be changed, which saves the production preparation time.

5. It can process complex profiles that are difficult to be processed by conventional methods, and even process some unobservable processing parts.

6. In the case of multi variety and small batch production, the production efficiency is higher, which can reduce the time of production preparation, machine tool adjustment and process inspection, and reduce the cutting time due to the use of the best cutting amount.

Production process

Quality Control

In Yonglihao, every staff emphasizes quality is first. Testing report and samples of all products will be kept by our quality control department.

>> Receiving inspection to raw material

All materials must be provided with suppliers' certificates, and have to pass the receiving inspection before starting production. Occasionally, material samples will be sent to independent lab for specific test to meet customers' demands. All materials have to be tagged and classified, so the original source could be traced at any time during production processes.
>> Producing inspection

Every phase of production processes will be monitored by producing inspection. The first product shall accept test in every phase of production process. Only it completes the test and confirmed by quality control manager, mass production could be operated. Every producing operator will implement constant tests during production processes, including size-measuring, observing the appearance. 
>>Final inspection

Products of Yonglihao only can get out of the warehouses after all files signed and sealed.

Warehouse and Shipment：

FAQ:

Q1:Where can I get product & price information?
A1:Send us inquiry e-mail or add us whatsapp, we will contact you as we receive your mail.

Q2:How long can i get the sample?
A2:Depends on your specific items, within 3-7 days is required generally.

Q3:What kinds of information you need for quote?
A3:Kindly please provide the product drawing in PDF, and will be better you can provide 3D drawing in STEP or IGS format.

Q4: What shall we do if we do not have drawings?
A4:Please send your sample to our factory, then we can copy or provide you better solutions. Please send us pictures or drafts with dimensions (Length, Hight, Width), CAD or 3D file will be made for you if placed order.

Q5: How can we know the chemical component of your products is according to our request?
A5: When we offer samples or batch parts, we will also send you our material list from our material factory, it shows more detailed.

Q6: How to guarantee your final size can meet our drawing request?
A6: we will make moulds according to your 3D drawing. And we also do sampling when batch production start, to make sure the final dimension can meet your request.

Q7: How to make sure the color after painting or powder coating can be correct?
A7: We have color card with different color number, such as RAL9016, we will contrast the sample surface and color card, to make sure the final surface effect is correct.

Q8: Generally, how do you packing the goods?
A8: normally, for inner package: the goods is nude, for outer package: carton + plywood. 

Q9: If we find the defect products exist in the batch parts, how to do?
A9: Yes,your caution is very good, in fact, when batch production, we need do sampling. Before shipment, we also do testing to make sure the quality is ok. If you found several defect product exists, pls take photos and send your quality feedback, we will check and send you qualified products. But pls be assured that our products is qualified, unless caused by the worker's mistake to place.
