铸件尺寸(单位:mm): 160 x 160 x 15 mm

压铸机品牌：

模具生产商：
Ningbo Shengji Machinery Co., Ltd.

铸件使用场合、工作条件：
This casting is used for Sanitary Hardware. Its installed in Wash Rooms with high humidity and temperature, making it susceptible to Corrosion. As a requirement, after polishing, we electroplate as per ASTM B456 service level 2 and its ASST requirement is 24 hours.

产品技术难点说明:
Sensor Plate

• Very Large Size (160 x 160) & Thin Wall (2.5mm)
• If filled from one edge -Long travel and bends
• Large Window to Obstruct smooth flow of metal
• Six locks and 4 tabs have to be provided in tool.

Sensor Activation Button

• Perfect round ends required
• The “Stiffners” provided to reduce weight for ABS sticks in “Tool Fixed half”- casting warps.
• Round ends have “sharp fins”-cause excessive deposition
• Product geometry does not provide “Jig Holding” position

铸件重量(单位:kg)：0.520 Kg

合金品牌及牌号: Zamac 3

产品典型特点：
Customer’s product is used in Wash Rooms. It is “sensor activated” water flushing system. The product facia during initial launch was made by ABS plastic. Product was not well received. DST Industries converted the “Face plate and activation button from ABS to Zinc Alloy, wherein no other customer parts were modified. All characteristics of ABS part were incorporated in Zinc alloy casting.
The product has been successfully relaunched and well received.

产品生产关键要求：
Casting requirements : The surface should be free from any visual defects. It should be dense, so that it can be mirror polished to perfection. The casting should not twist while ejection. Two ends height difference on surface plate should not be more than 2mm. The 4 tabs creates surface depression during die opening. This is to be avoided.
Electro Plating requirements : Cu-Ni-Cr Plating as per ASTM B456 service level 2. ASST requirement is 24 hours.

针对技术难点采取的措施:
Sensor Plate
• Used The “large window” as feed position
• Used “IZA developed taper runner theory” to design accelerated flow to fill thin sections.(yield was 85% )and no vacuum was used.
• 6 “Inclined ejectors” were provided
• Design of “Inclined ejectors” was modified to prevent warpage
• Tabs were rounded to reduce depositions


Sensor Activation button

• Geometry modified – Stiffners removed from certain sections
• Geometry modified – Sharp edges at both ends were rounded
• Special tool & fixture made to create round ends for smooth movement
• ABS to Zamac3 redevelopment successful
• Product Re-Launched and Well Received by Market
