Conclusion
1. Each piece of product saves 1.17 CNY and the annual output is 6600×64=422400PCS, so, there are 494,208 CNY costs are saved in total.
2. The project result is beyond the expectation, thus meeting the demands of Luos.
Existing Brand | Doush | |
Runner | ||
Ruffles with uneven thickness are formed and cannot be removed. | Each product comes with 3g injection residuals that can be rapidly removed by tools. | |
Sprue | No pictureGenerally, the injection volume should be 30g more than that the sprue can contain. | No picture |
Flash | ||
The flashes are bonded together and can be removed in flake shape during demoulding. Each mould comes with 58g flashes. | Each mould has 18g flash residuals. | |
Deflashing 1 | ||
The flashes at the parting line should be removed by scalpel. | No flash at the parting line | |
Deflashing 2 | ||
The shear is used to remove the flashes at the edge and center of moulds. | The flashes at the edge and center of moulds can be directly torn down by hands. This work can be finished by vulcanization workers and does not need post processing. | |
Drilling | ||
Drilling and cleaning are required for screw installation. | Cleaning is not needed. |
