[Points to Consider During POM Injection Molding]
- The biggest consideration when performing POM injection molding is safety.
- When setting conditions for POM, to prevent burrs, the molding temperature, injection speed, and holding pressure should not be set too high.
[Methods for Fixing Workpieces for Machining (Regarding the Use of Vices)]
- Since vices are side clamps, they cannot be securely fixed if there are no parallel surfaces on the fixing side.
- If the clamping force is too strong, warping may occur, and if it is clamped lightly, machining accuracy may vary, potentially causing the workpiece to come loose and be thrown off.
- To take advantage of the benefits of starting machining without creating a fixing jig, it is important to understand the disadvantages well and use it accordingly.
[Standardization of Quality Through the Use of Gauges (Inspection with Ring Gauges)]
- When measuring with calipers or micrometers, measurement errors can occur due to variations in force applied by different individuals. However, with ring gauges, anyone can use them, and since the judgment is only about fitting and stopping, there is no need to worry about measurement errors.
