Chlorinated paraffins are excellent stamping lubricants

Obviously, volume is important in any metalworking industry. The number of stamping parts processed through the washer determines how often the tank needs to be drained, cleaned and refilled. This plays a significant role in how costly the process is. Customers must choose from a combination of, in-process methods to remove the paraffin from the washer. Chlorinated soil drops to the bottom of the tank after a certain level of saturation is reached. This soil accumulates on the bottom of the tank and can cause serious problems for the washer heater elements by coating them with sludge. Water heating systems, regardless of whether they are electrical, gas, or steam, can be adversely affected by the paraffin sludge. The sludge coats the device, insulating the heat, and preventing the system from warming the water. The stress from this insulation effect causes the devices to eventually fail. Pump inlets, also located at the bottom of the tank, are clogged by the sludge, which prevents the flow of fluids into the tank and stresses the pump motor. It is critical to avoiding these situations. One method for redirecting the fallout of sludge is to employ a false bottom in the tank. The bottom must stretch the length and width of the tank to be effective. For efficiency, the bottom should not rest on a horizontal level plane. Rather, the bottom can be slanted so that the sludge can be reached before reaching the bottom, and also so that it falls to one side of the tank for easier removal. Gravity, or a system of spray nozzles, can encourage the sludge to fall onto one side of the tank. The second and third factors to consider are whether the supplier has experience in designing, and building precision metal machining parts dies. A supplier who can design and build precision metal machining parts dies will inevitably be much more qualified to succeed in stamping parts your components than a supplier without these capabilities. A supplier who designs precision metal stamping parts dies understands the importance of having certain features and stations in a die which will result in the highest efficiency and quality during the stamping operation. A supplier who is adept at building and developing precision metal stamping parts dies has the added benefit of being able to troubleshoot any unplanned stamping issues. The fourth factor to consider when selecting a precision metal welding parts supplier is the supplier's capability in the area of process control. If a supplier is ISO-certified, this provides a certain layer of insurance that control processes are in place. Understanding how a precision metal welding parts supplier creates and works with control plans is important. Visiting the supplier and seeing their Quality system in operation is probably the best way to evaluate a supplier's attention to process control. Determining the role of the Quality technician at a supplier will speak volumes to assuring that a job will end up successful. Evaluating a supplier's investment in inspection equipment is an additional indicator of potential success. Next, it is beneficial to determine if a precision metal welding parts supplier offers a die maintenance program. This will result in maximizing the life of the die and will optimize your total life cycle cost for your stamped component. A good die maintenance program will address die and die component inspection, synchronization and adjustment of die/press/peripheral equipment, proper assembly/disassembly techniques, die component replacement schedules, etc.
