Easy punching of large stampings

When the factory develops and produces plastic spinning machinery, there are many large-scale stamping parts with a length of 1.5m or more and a weight of 1-35kg. There are many holes with different hole shapes and different hole pitches on these stamping parts, and some holes are required to be relatively high, which brings great difficulty to the stamping process. At the beginning we wanted to use CNC punching machine. The equipment in the nearest city can only process 4mm thick plates, and our parts have a maximum thickness of 10mm, and the cost is too high. Later we solved this problem well with a simple method. Take the parts shown in Figure 1 as an example for explanation.

Chemical Industry Mass Flow Meter

Sealand is a professional supplier of Chemical Mass Flow Meter, Chemical Mass Flowmeter, Chemical Flowmeter, Chemical Flow Meter, Chemical Coriolis Meter, ATEX, IECEx & CE approved.


The meter can work with a pulse receiver(Count). The connection is as follows. The resistance value is up to the cable length & the max. input pulse frequency of receiver. Current 10mA is suitable for most receivers; however, you can reduce the resistance value when the cable is long. The max. current could be 50mA. Please use the fixed frequency output function to check if the cable length & resistance value is suitable.

Please check following items before operation, and operate according to relevant rules. a) If the meter is damaged during shipment and installation;
b) If the voltage is same as marked on nameplate;
c) If the fuse is correct;

d) If the meter is grounded properly.
e) If the Meter SN on the nameplate of sensor and transmitter are the same.
If everything is fine, please open all valves, make the pipeline full of liquid and then power on the meter for warm-up for 20min before operation. Finally, conduct zero calibration after first start, and shall do it again if the meter is moved to another site.
Preparation for zero calibration:
a) Power on the meter for approximately 20min for warm-up;
b) Run the process fluid through the sensor until the sensor temperature reaches the normal process operating temperature.
c) Close the shutoff valve downstream from the sensor.
d) Ensure that the sensor is filled with fluid and the process flow has completely stopped.
