3402-05 Machine shops, N.O.C., job shops, tool sharpening, mobile welding shops, storage battery manufacturing, assembly or repair, multimedia blasting, die casting, and heat treating metal

Applies to:

Businesses with general machine shop operations not covered by another class. This classification also applies to the manufacture, assembly or repair of storage batteries, tool sharpening, multimedia blasting, die-casting and heat-treating.

Work activities include, but are not limited to:

• Tool sharpening;

• Welding;

• Mobile welding shops;

• Machining;

• Multimedia blasting:

- Multimedia (such as, but not limited to, glass, plastic and sand) blasting operations which strip paint or other coatings from metal or fiberglass. Most of the blasting operations in this classification are done on automobiles, but it also applies to establishments that perform blasting on items such as, but not limited to, barbecue grills, and cast iron pieces. Multimedia blasting processes in this classification are performed in a shop, use less air pressure and media with softer finishes than other blasting operations.

• Die casting:

- Die-casting is a manufacturing process for producing accurately dimensioned, sharply defined metal products, which are referred to as "die castings." "Dies" are the steel molds used to mass-produce the product. The process begins when ingots of various metal alloys are melted in die casting machines. The machine forces the metal into the die under hydraulic or pneumatic pressure. The casting quickly solidifies in the die, and is automatically ejected by the machine, and the cycle starts again. The castings are cleaned by grinding or sanding, which also removes any excess metal "flash." Many die casting manufacturers maintain their own machine shop for making the dies. Die making, when done as a part of die casting operations, is included within the scope of this classification.

• Heat treating:

- Process may use computer numeric controlled (CNC) ovens or furnaces. The oven may heat up to 1200 degrees Fahrenheit and a furnace may heat up to 2000 degrees Fahrenheit. The metal(s) is placed on a platform; the platform is hydraulically moved into the first chamber and the door is automatically closed. At this time, the oxygen is burned from the chamber. Then the second chamber door is opened and the metal enters the oven/furnace. Depending upon the specifications, the heat treating process usually takes six to sixteen hours. When the metal is finished in the heating chamber, it returns automatically to the first chamber. Then the platform lowers and the metals are dipped into a cooling agent. Once the metals are cooled to room temperature the platform rises, the door opens, and the materials are removed. The process is essentially the same without using computer numeric controlled (CNC) heat-treating equipment except that, rather than being hydraulically operated, the machine operators move the metals through the system. Many establishments do not produce a product, but heat-treat a variety of products to customer specifications.

• Storage battery, manufacture, assembly or repair:

- Lead ingots, weighing 20-25 pounds, are melted and poured into a mold or casting machine. After the grids are cooled lead oxide is then pumped onto each side of a grid and cured by baking in an oven of about 300-400 degrees F. The plates are then assembled by placing a negative separator (zinc) between a positive separator (copper), and so forth until there are enough of these cells to form the battery. Next, they are sent to a burning machine that cures the paste and plates. After the burning process, the plates are placed into a plastic or hard rubber box-like container and cured for two or three days. The plates are welded together and the top is attached to the body of the battery case with an epoxy glue. Diluted sulfuric acid is added to the battery and then it is put on a charger. The battery is then cleaned and packed for shipping.

Special note: The term "job shop" is an industry term that means the shop will produce products to customer specifications.
