Finished product inspectionToday, thanks to advances in industrial technology, mass-producing barbecue grills has become simple.Here’s a general guide to building a simple charcoal barbecue grill.

Design and Drawing
First of all, design and drawing are needed to determine the shape of the barbecue grill, size and structure, as well as the required materials and tools.
Material Selection and Preparation
According to the design drawings, select suitable materials, such as steel, aluminum, etc., and carry out preparatory work such as cutting, bending and drilling.
Selection and preparation: According to the design drawings, select suitable materials, such as steel, aluminum, etc., and carry out preparatory work, such as cutting, bending and drilling.
Cold rolled iron (actually cold rolled steel)
Cold rolled iron is made by extruding a steel plate at room temperature into a sheet of 0.1-8.0mm thickness; the thickness of the main body of a conventional barbecue is generally between 0.4-1.5mm thickness.
Stainless Steel (304 Stainless Steel)
High quality BBQ grills are usually made of 304 stainless steel. Due to the properties of stainless steel, stainless steel grills are more corrosion resistant and durable.
Stamping and bending:
The material is cut by means of different sized punches. This step usually involves molds, and since each grill has a different shape, multiple sets of stamping molds are designed.
Welding and assembling
Welding and assembling the pre-prepared parts to form the basic structure of the barbecue grill.Welding and assembling: Welding and assembling the pre-prepared parts to form the basic structure of the barbecue grill, which needs to ensure the welding quality and solid structure.
Surface treatment
After the barbecue grill is completed, surface treatment is required, such as cleaning, grinding and painting, etc., to ensure that the barbecue grill is of good quality and solid structure.
surface treatment, such as cleaning, grinding and spraying, etc., to ensure that the appearance of the barbecue grill is beautiful and durable.
Plastic Spraying/Electrostatic Spray
Plastic spraying is a physical surface treatment. Cold rolled steel rusts easily without treatment. Through the surface treatment can be plated with coating, at the same time can hide the welding points, more easily to the furnace body spray different colors of plastic spray powder, etc..
Plastic spraying is mainly the use of thermosetting powder coating, the color can be done in a variety of ways. Through electrostatic spraying adsorption on the surface of the workpiece by 200 degrees 10 minutes after curing the surface treatment process.
The surface film of high-temperature spraying will be thicker than electrophoresis. The disadvantage is that the thickness of the back side may not be consistent and the corners may not be covered completely.
Conventional plastic powder can only withstand temperatures up to 200 degrees Celsius, and due to the characteristics of the product, Fire pit will be sprayed with high temperature resistant plastic powder that can withstand temperatures up to 600 degrees Celsius.
Electrophoresis
Mainly applied to the surface of the furnace; electrophoresis belongs to the ion convection, electrochemical reaction leads to the accumulation of paint layer, in the oven at (165 ± 5) ℃ temperature baked 40 ~ 60min.
The surface is smooth with paint film, the film is relatively thin but uniform. One of the electrophoretic paint high temperature resistance within 300 degrees Celsius.
Advantages of electrophoresis: water-based paint environmental protection, high paint utilization, good corrosion resistance, high processing efficiency, low cost per unit area of paint; electrophoresis due to the contact surface of the whole, theoretically, will be more comprehensive than the spraying coverage (welding corners, etc.) is less likely to be due to the coating is not full of the problem of the oven rust.
Disadvantages: single color and more difficult to adjust at will, large investment in pre-production equipment, only suitable for products that can conduct electricity, high temperature curing is required.
Electroplating
A conventional grill will have two grills. One of them is used to hold food (B); the other is used to hold charcoal (C), so as to avoid charcoal clogging the bottom air outlet. One of the food net due to direct contact with food, the top of the plating in Europe and the United States will need certification requirements, such as grill net needs to pass the LFGB test. The lower net is generally not required. (Note: Food grids need to have LFGB certification, which mainly measures the migration of heavy metals)
Electroplating is the process of plating a thin layer of alloy on a metal surface using the principle of electrolysis.
Usually food grills are chromium plated (the coating is attached by electroplating and the metallic chromium on the surface of the chromium plated parts is harmless. Electroplated trivalent chromium is a trace element needed by the human body. Hexavalent chromium is toxic).Due to cost control, the lower grill is galvanized.
Test and quality inspection
After finishing the barbecue grill, it is necessary to carry out test and quality inspection to ensure that the use effect and quality of the barbecue grill meet the requirements.
After finishing the barbecue grill, we need to carry out test and quality inspection to make sure the use effect and quality of the barbecue grill meet the standard.
Packing and shipping:
Finally, the barbecue grill will be packed and shipped to ensure that the barbecue grill is not damaged during transportation.
transportation process is not damaged.
