Electric ovens are popular for their convenience, ease of use, and the ability to provide consistent and precise temperature control. They are widely used in both residential and commercial kitchens for baking a variety of dishes.

Electrical resistance type heaters are used in the baking oven for drying Teflon coating and paints of non-stick cookware. Most of the ovens are continuous conveyor-type ovens in which cookware with Teflon coating and paints are heated at about 400-450 C for about 30 minutes cycle time. These ovens are provided with recirculating fans of 1-2.5 hp for hot air circulation internally. Most of the ovens have on-off control

Spot welding

Spot welding is a resistance welding process used to join two or more pieces of metal together by applying localized heat and pressure. It is a versatile and widely used welding technique, particularly for thin sheet metal applications, due to its efficiency, precision, and minimal heat distortion.

Working Principle

Spot welding involves placing the metal pieces to be joined between two electrodes, typically made of copper or copper alloys. A high-current electrical pulse is passed through the electrodes, causing localized heating at the point of contact between the electrodes and the metal pieces. This intense heat creates a molten pool of metal at the contact points, and the applied pressure forces the molten metal to fuse, forming a strong weld.

Advantages of Spot Welding

Spot welding offers several advantages over other welding techniques:

• Localized Heating: Heat is concentrated at the weld point, minimizing heat distortion and affecting surrounding areas.
• Precision Welding: Precise control of the welding parameters allows for accurate and consistent welds.
• High Efficiency: The rapid heating and cooling cycle enables high welding speeds and production efficiency.
• Minimal Heat Distortion: The localized heating minimizes warping and deformation of the metal pieces, especially important for thin sheet metal applications.
• Versatility: Spot welding can be used to join various types of metals, including steel, aluminum, and copper.

Applications

Spot welding is widely used in various industries, including:

• Automotive Manufacturing: Spot welding is the primary method of joining sheet metal components in automotive bodies.
• Appliance Manufacturing: Spot welding is used to assemble various components in appliances, such as refrigerators, washing machines, and stoves.
• Aerospace Industry: Spot welding is used in the construction of aircraft and spacecraft due to its precision and strength.
• Electronics Manufacturing: Spot welding is used to join electronic components, such as wires and circuit boards.
• General Metal Fabrication: Spot welding is used in various metal fabrication applications, such as joining metal frames, brackets, and enclosures.

Conclusion

Spot welding is a versatile, efficient, and precision welding technique that plays a crucial role in various industries. Its ability to join thin sheet metal without causing significant heat distortion makes it an essential tool for manufacturing a wide range of products. As technology advances, spot welding continues to evolve, incorporating new features and advancements that enhance its capabilities and expand its applications.

Most of the components in kitchenware are welded using spot welding machines which lead to the proper joining of kitchen baskets and various stove components. Presently these spot welding machines are transformer
controlled with capacities ranging from 5-10 kVA. Spot welding machines are also used to weld SS202 blades on SS 202 slicer body

Grinding and buffing

Grinding and buffing are two processes used in metalworking and other industries for shaping, finishing, and polishing materials. Here’s an overview of each process:

Grinding

Purpose:

• Grinding is a material removal process that involves the use of abrasive particles to remove excess material from a workpiece.

Equipment:

• Grinding Machine: A machine equipped with an abrasive grinding wheel or belt, often used to shape, sharpen, or finish metal objects.

Process:

1. Material Removal: The abrasive particles on the grinding wheel or belt remove small chips of material from the workpiece, changing its shape or surface finish.
2. Precision Shaping: Grinding is often used for precision shaping of metal parts, ensuring they meet tight tolerances.

Types of Grinding:

• Surface Grinding: For flat surfaces.
• Cylindrical Grinding: For cylindrical surfaces.
• Centerless Grinding: For outer diameter grinding without using a spindle.
• Tool and Cutter Grinding: Sharpening and shaping cutting tools.

Materials Used:

• Grinding wheels are made of abrasive particles bonded together. Common abrasives include aluminum oxide, silicon carbide, and diamond.

Buffing

Purpose:

• Buffing is a finishing process that uses a soft cloth wheel or abrasive compounds to enhance the surface of a workpiece, giving it a smooth and shiny appearance.

Equipment:

• Buffing Machine: Typically consists of a motorized wheel covered with a soft material, such as cotton or felt, and various polishing compounds.

Process:

1. Application of Abrasives: Buffing compounds are applied to the rotating wheel.
2. Polishing: The rotating buffing wheel is pressed against the workpiece, and the polishing compounds help remove fine scratches, oxidation, or imperfections from the surface.
3. Finishing: The process continues until the desired level of smoothness and shine is achieved.

Types of Buffing:
