Lighter production process

2024-04-03

The production process of lighters usually includes the following main steps:

Material selection. The main raw materials of lighters include metal, plastic, rubber, glass, quartz, silk, chemicals, etc. The metal part mainly includes aluminum and copper, and the plastic part is polyethylene, nylon, ABS, etc., and rubber is mainly used as a buffer to absorb impact. material. Large quantities of oil (such as liquid petroleum gas) and other auxiliary materials are also required.

Molding. The metal part is processed by multiple processes such as sheet metal processing, pressing, stretching, punching and shearing, polishing, etc. The plastic part is processed by injection molding, extrusion, blow molding, etc. After molding, fine adjustment and cutting are required. The rubber part is processed by molding and other processes.

Oil filling. The formed lighter needs to be filled with oil, which is a very important link in the lighter manufacturing process. Liquid petroleum gas is the fuel used in lighters, and attention should be paid to the control of the proportion and the filtration of oil during the oiling process.

Assembly. After oiling, the lighter needs to go through multiple assembly processes, including assembly of mechanical parts, fire pipes, stone cores, shells, etc. These small parts need fine assembly.

Acceptance. After the assembly is completed, strict quality inspection is required to check whether every detail meets the requirements, especially the ease of operation, sealing, spark strength and rigidity.

Packaging. After passing the quality inspection, the lighter can be packaged, including containers, plastic bags, packaging boxes, etc. All kinds of lighters have their own packaging standards, but the purpose of unification is to ensure the integrity of lighters and avoid breakage and damage during transportation.
