A composite thread protector that will be practical under normal as well as frigid temperature conditions of usage is formed by deep drawing a seamless metal shell wall, using a threaded die to define a mold cavity with the metal shell wall, forming and setting a synthetic elastomeric shell wall within the mold cavity in an adhering assembled relation with and along the metal shell wall with threading that is complementary with threading of the die, removing the assembly by unscrewing it with respect to the threaded die, and subjecting the assembly to heat treatment to cure the elastomeric shell wall and provide a composite protector having a cast urethane elastomer wall in a secure adhering encapsulating relation on the metal shell wall.

Compostable bags are designed to disintegrate and biodegrade quickly and safely, when composted in a professionally managed composting facility. It eliminates the need for bag removal, eliminate the deterioration of the compost from imperfect bag separation, and eliminate the cost of used-bag disposal.

Compound Metering Pumps are recommended to all vibratory mass finishers. Automatic compound dispensing assures consistent processing. A flow-through solution cleans chips, flash, soil, abrasive fines, oils out of the process chamber. And the most economical way to dispense vibratory finishing compound is to use a flow-through utilizing a compound metering pump. They are used with liquid compounds that you can set to a desired amount of both compound and water. Once set to the desired compound and water amount, no other action is needed. A flow-through liquid compound system is superior to hand additions of dry or pre-mix compounds which are generally wasteful and difficult to use. Metering pumps are not used for abrasive compounds.
