Other Material Vacuum Forming Machine means our Vacuum Forming Machine can be suit many plastics like Acrylic, ABS, PVC, PET, Poly styrene, Kydex, and so on. plastic sheet is fed from a roll or from an extrude into a set of indexing chains that incorporate pins, or spikes, that pierce the sheet and transport it through an oven for heating to forming temperature. The heated sheet then indexes into a form station where a mating mold and pressure-box close on the sheet, with vacuum then applied to remove trapped air and to pull the material into or onto the mold along with pressurized air to form the plastic to the detailed shape of the mold.

1 Before installing the instrument into the process piping, all installations should be removed and checked for shipping damage.
2 flowmeter to prevent the rubber band in the indicator fixed in the indicator, before the wiring should open the left cover of the indicator to gently remove it, do not change the pointer position.
3 Open the right cover of the indicator. After the cable passes through the cable lead-in device, connect it according to the wiring diagram of the rotation angle transmitter, tighten the pressure nut to fix the cable, then tighten the fastening screws of the left and right covers to make the indicator Waterproof and dustproof.
4 The upstream and downstream pipelines of the instrument should be the same as the caliber of the instrument. The connecting flange or thread should match the flange and thread of the instrument. The length of the straight pipe upstream of the instrument should be guaranteed to be 5 times the nominal caliber of the instrument, and the length of the downstream straight pipe should be a lot of h2. At 250mm.
5Because the instrument's measurement mechanism uses magnetic transfer, to ensure the performance of the instrument, no ferromagnetic material is allowed to exist at least 100mm around the sensor installation.
6 Before the instrument is installed, the process piping should be purged to prevent the ferromagnetic material trapped in the pipe from adhering to the instrument, affecting the performance of the instrument and even damaging the instrument. If it is unavoidable, a magnetic filter should be installed at the entrance of the instrument.
7 The instrument for measuring the gas is calibrated under special pressure. If the gas is directly discharged to the atmosphere at the outlet of the instrument, it will cause a pressure drop at the float and cause data distortion. If it is such a working condition, it should be A valve is installed at the outlet of the instrument so that the desired flow rate can be set. When the calibration pressure is maintained on the float, the gas will expand at the valve.
8 The installation form of the instrument is divided into vertical installation and horizontal installation. If it is a vertical installation form, the straightness of the instrument should be guaranteed to be better than 1%; if it is a horizontal installation form, the horizontality of the instrument should be guaranteed to be better than 1%.
9 The instrument installed in the pipeline should not be affected by stress. The outlet and inlet of the instrument should have proper pipeline support, which can make the instrument in the state of minimum stress.
10 When the product is associated with a computer or the like for calibration or other operations, it must be carried out in a safe place.
Special Note: Before installation of the flowmeter, the spoils and welds in the pipe shall be sprayed clean according to impurities. If the liquid contains solid impurities, the corresponding filter shall be installed between the valve and the straight pipe.
Shielding and grounding: To ensure the best electromagnetic compatibility of the system, shielding and grounding are very important, especially bus cables. Keep the cables shielded as continuously as possible.
For the safety zone, the cable should be grounded as much as possible according to conventional requirements.
In hazardous locations, ensure that there is sufficient equipotential bonding between the safe location and the hazard within the entire bus range. In this case, multiple grounding is advantageous.
