Advantage of die casting

1. The production efficiency is high, and the production process is easy to realize mechanization and automation. Generally, the cold chamber die-casting machine casts 50~90 times per hour on average, while the hot chamber die-casting machine casts 400~900 times per hour on average, with high production efficiency.

2. Die castings have high dimensional accuracy and surface quality. The general tolerance grade of die castings is it13~it15 in gb/t 1800-2009, and the higher accuracy can reach it10~w 11. The surface roughness is 3.2~1.6um, and locally 0.8um. Because of the high dimensional accuracy and high surface quality of die castings, die castings with low requirements can be used directly, avoiding machining or using less machining, improving the utilization of alloy and saving a lot of machining costs.

3. Die castings have high mechanical properties. The metal melt cools fast in the die casting mold and crystallizes under pressure. Therefore, the layer near the surface of the die casting has fine grains, dense structure, high strength and hardness.

4. It can die cast complex thin-walled parts. Die castings can have complex part shapes, and the wall thickness of parts can be small. The minimum wall thickness of aluminum alloy die castings is 0.5mm, the minimum wall thickness of zinc alloy die castings can reach 0.3mm.

5. Parts of other materials can be embedded in die castings. In this way, valuable materials and processing costs can be saved, parts with complex shapes can be obtained, the performance of parts can be improved, and the assembly workload can be reduced.

6. Compared with sheet metal parts, the shape of die-casting parts can be more complex, and the wall thickness of parts can be changed. One die-casting can replace several sheet metal parts, so as to simplify the product structure.

7. Compared with plastic parts, die castings have advantages in strength, conductivity, thermal conductivity and anti electromagnetic radiation.

8. Compared with machined parts, die castings are light in weight and low in processing cost.

9. Compared with other casting methods, die-casting products have high dimensional accuracy, good surface quality and high production efficiency.
 

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
 

 

RFQ:

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.
