Applications:

In considering injection moulding as a prototyping solution, there are many factors that have to be addressed and many alternatives that must be considered. The most important issue to consider is whether the production intent material is really a requirement, if it is, then understanding the available time and attention to the CAD model are both paramount.

Process Features
Accuracy
Tolerances vary depending on material, filler, tooling strategy, geometry etc. It is always recommended to identify critical dimensions and make these available at the quotation phase.

Minimum Feature Size
With the advent of micro moulding any comments on minimum feature sizes became redundant! This is linked to a number of features in the geometry as well as the tooling strategy selected. 

Machine sizes
The most common sized moulding machine is around 80 tonnes, and access to presses up to 250 tonnes is straightforward. From 250 to 1000 tonnes access becomes more difficult and more expensive, but remains feasible.

Post processing
Negligible post processing is usually required, unless quantities are sufficiently low that some features are to be post machined to minimise tooling costs. Resins are pigmented and any texturing is included in the tooling.

Specifications:

Some critical issues to clarify before searching for tooling are
1. The realistic leadtime that you seek. Speed will cost a premium, so an accurate appreciation of the available leadtime after making allowances for the time to raise a purchase order, is a necessity. 
2. The number of parts required both initially and over the life of the tool. This is important as if the initial batch is small enough it may be more economic to meet each requirement from a different solution. 
3. Critical dimensions and their associated tolerances as these may preclude some approaches immediately. 
4. Textures, are they required and if so where and to what specification. 
5. Changes will frequently occur and most suppliers acknowledge this. However, if there are recognised areas of high risk within the tool, these should be highlighted to the supplier. This may result in a different approach and save time later on, if changes are indeed required. 
6. Materials, evaluating different materials (or fillers) may be a possibility so long as there is an appreciation of the effect this can have on shrinkage and hence dimensional accuracy.
If you are new to injection moulding it is best to involve a supplier from an early stage as this will ensure that the design matures as efficiently as possible and avoids any last minute delays.

Highlights
We provide very low cost Rapid Plastic Molds and Plastic Molding to challenge some high quantity vacuum casting applications and delivery can come down to 2 weeks or less. These two issues cannot always be achieved simultaneously, however injection moulding must now be considered as a prototyping solution with the potential to also address early production requirements. 
The greatest upside to using this process is that it delivers the production intent material and, once the tooling is in place, parts are available quickly and at low cost.

 

Description:

AIRCRAFT MODEL STAR(INTERNATIONAL) CO., LIMITED founded in 2011,at DongGuang GuangDong, 2000 square meters',Specialize in,develop,produce,Foreign trade,rc model,plane model,quad copter UAV plane,precision component metal accessories process etc.

Aircraft model star( international) co., limited from ZXmade team. ZXTECH (HK) CO.,LTD  was set up by Doctor Yang (Young) in March, 2005. ZXTECH started rapid tooling manufacturing since it was founded and got involved in rapid CNC prototyping one year later, after another year endeavor, ZXTECH decided to focus on rapid precision engineering for complex prototyping to improve its competitiveness, which has led the Chinese RP field since the second half year of 2007. Now, ZXTECH has combined rapid tooling, rapid prototyping and rapid precision engineering technologies in the rapid manufacturing field, which is unique in China. In September, 2008, a very famous western-owned prototyping company found ZXTECH and made ZXTECH as their key supplier for precision prototyping, metal forming and machined extrusion parts for exports. This has helped ZXTECH greatly in improving their quality standards and management to meet standards, international standard, but with 100% Chinese costing.
