Special high-temperature chipless extrusion drilling tools - Formdrill drills generate high frictional heat due to high-speed rotation and axial pressure. The temperature of the tool can reach 900 degrees, and the temperature at the processing point can reach 700 degrees.
The material at the processing point is in a "superplasticity" state, and the tool displaces this material and shapes it to form a bushing. The height of the bushing can be 3-4 times the thickness of the original workpiece.
The bushing can be used as a nut after tapping, and the number of teeth and strength of the thread are significantly increased. It is the best alternative to welding nuts. Bushes can also be used as brazed, welded or brazed joints.
High-temperature chipless extrusion drilling process can be widely used in a variety of black and non-ferrous metals, including low-carbon steel, stainless steel, copper, brass and aluminum, the maximum thickness of metal materials is 12 mm. In general, the high-temperature chipless extrusion drilling process is applicable to all malleable materials. Standard drill bit diameter from small to large, complete specifications, a maximum of 25.4 mm. At the same time, according to the needs of customers, production of special specifications of the large diameter drill.
No special equipment is required. Ordinary drilling machines, milling machines, or CNC machining centers can be used. Chipless Extrusion Hot Melt Forming Bits Formdrill drills are especially suitable for industrial automation because of their advantages of no chip processing, accurate drilling, and long service life.
High-temperature chipless extrusion drilling is simple and easy, and it can also be used for experimental sample processing.
Formdrill bits are all swarf-free during the drilling process without any cuttings.
vacuum formed trays is one of plastic trays which produced by thermoforming process. Frist step is heating a sheet of plastic then plastic sheet was stretched over a mold over a mold before being forced against it by a vacuum,the plastic tray is manufactured.
Diffirence with standard plastic trays with fixed cavities, the benefites of using vacuum formed trays comes from customized options avaiable.With advantage of lightweight, easy to operation, saving space,welcomed by most of customer.
vacuum formed trays can effective protect your parts or components.They are wide used on packaging trays,lastic tooling trays, precision device trays, medical trays, cosmetic trays, pet product trays, hydroponic planting trays, transportation trays, automotive parts trays etc.
