Product Description

Manufacture Process

1. Review the part design,drawings and quality standard from clients.
2. Mould and Tooling design & manufacturing
3. Mould and Tooling testing & confirm the sample
4. Die casting raw castings
5. Surface treatment: Trimming,Deburring, polishing, cleaning, passivation & power coating and other requirement from Customer
6. Precision machining: CNC lathes, milling, drilling, grinding etc
7. Full Inspection
8. Packing
9. Delivery

How to determine the optimal number of cavities?
This is not a simple choice, but a financial and engineering calculation problem. We will evaluate together with the client:

1. Life cycle total demand: What is the expected total output of the product?
2. Mold investment budget: For every additional cavity, the mold cost increases by about 15% -30%, but not in a straight line.
3. Injection molding machine capability: What is the required clamping force (tonnage) and injection volume? The number of cavities is limited by the machine specifications.
4. Part size and mold size: Can the mold fit into a standard injection molding machine? Will the template be too large?

Allowable production cycle: How fast is the delivery speed required by the customer?

Quality Control

1) Checking the raw material after they reach our factory------- Incoming quality control ( IQC)

2) Checking the details before the production line operated

3) Have full inspection and routing inspection during mass production---In process quality control(IPQC)

4) Checking the goods after they are finished---- Final quality control(FQC)

We strictly control production process by using computer to monitor 24/7, in order to enhance and stable the production quality. VCU has its own highly qualified QC team equipped with all necessary and state-of-the-art testing equipment to be able to perform 100% inspection in order to ensure the best quality products that will be delivered to all of our customers.

Our Advantages:

1. We are the biggest lost foam mould manufacturer in China, we focus on high challenge lost foam mould and we have large gantry machining centers,30 sets imported high speed machining center,more than 40 sets general machine tool equipment;
2. We have 36 senior mould designers, to ensure reasonable / safety / high efficiency mould design and ensure the fast mould delivery and rational mould structure, make the process more safer and the production efficiency more higher;
3. We using numerical control machine tool to manufacture the mould cavities, to ensure a even thickness ;
4. We using ZL104 Aluminium to casting the mould, to manufacture a high strength mould;
5. For the big mould, we using Ø22*1 copper tube as cooling pipe, with water spray system, to get a nice cooling effect;
6. We Have (TEF10N) coating on the mould surface, it can reduce the friction, anti water/static electricity/acid-base/high-temperature, with this we can ensure the pattern has smooth surface without distrotion, and easy to demould;
7. All the screws we using stainless steel screw, easy to disassemble during maintenance;
8. For the big mould chest, we using 18-20mm thick wrought aluminium plate, to offer high strenght cavity ;
9. For the complex mould which is difficult to demould, we can manufacture the automaitc mould with take out device ;
10. We produce the pattern sample to customer after finish the mould, when the pattern was qualified, then we do exceptance job for the mould ;
11. We have the Hexagon coordinate measuring instrument imported from the Switzerland to have a test make sure our mould qualified.

Company technicians can provide on-site guide mould assembly, test production, free repair and complete technology for lost foam casting proecss according to customer demands. With the business philosophy of "careful design, lean manufacture, best service, perfect quality", we strive to provide satisfactory products and services for customers. After years of development, our company has become the preferred mould suppliers of many lost foam casting manufacturers and the exclusive supplier.
