    Electroless nickel coating of confined spaces

    Hi, I am conducting some experiments with the electroless nickel (EN) coating of the free machining brass (high lead contain material, which is not good for coating but I must use this material). After surface cleaning and etching procedure, once the brass is submerged in the EN coating...

    Electroless nickel plating - surface preparation

    Hi, I am conducting the experiments with the electroless nickel plating of the brass (CZ121). I have read a lot of the literature about this process prior to the lab tests. All brass surface cleaning procedures that I have came across involve the electro cleaning (I understand why). However...

    PLC control programming for two heaters, TCK, s/s relays

    Hi, I would like to provide the PLC control for a scenario where the temperature in a machine, heated by the two electric heaters, is controlled with use of 1 TCK and 2 s/s relays. Please see draft “PLC4” sent attach. The TCK is fixed to the machine and is not in a physical contact with the...

    Connecting tip for TCK type K

    Hi, I need to connect my TCK type K to the brass component which has working temperature approximately 200degC. I intend to drill/tap a hole in the brass (M3) and fix TCK to it with a bolt. I wonder whether using ring crimp terminal as the tip for the termocouple would be a good option...

    Solution for electroless nickel plating works when electrictity is applied only

    Hi, I have a brass components (brass grade CZ121) which require electroless nickel plating (not electroplating). I cannot get electroless nickel coating for my brass component from regular coating companies because of its complex geometry. Along with air agitation, special jig is required to...

    Extruded polymer volume vs extrusion hole diameter and length

    Hi, I have the polymer (PP) extrusion die. The die includes 0.25mm diameter holes. The length of each extrusion hole is 2.5mm (L/D ration is 10). I need to decrease extrusion hole diameter from 0.25mm to 0.20mm. I would like to calculate how much less polymer (volume) will be pushed...

    Valve(s) for switching between vacuum and compressed air

    Hi, I do some rapid prototyping using simple pneumatic system. Please refer to the attached draft. As outlined on the draft, the air in the container is slowly pumped out (with vacuum pump, there is only little bit of air pumped out), with valve 1 opened and valve 2 closed, and then the air is...

    Tubular cartridge heater wattage

    Hi, I have a machine equipped with 2000mm long tubular cartridge heater (230V, 1600W, 4mm diameter). This tubular heater is sandwiched between the two steel plates (2000mm long) i.e. the heater keeps the steel components hot. My problem is that the temperature of the steel components varies...
