Welcome everyone to our factory, we will present the detailed production process to everyone as follows. Anyway,How does a pair of pliers go from a piece of metal casting to a complete pliers?
Forging
This is the most important process that decides the quality of the product. By the fine-tuned checking of product quality, if there are products with poor quality, we immediately stop production to prevent poor-quality products from being sent to the next stage of the process. Additionally, when there are requests from the post-process, we always improve the forging to meet such requests.
Drilling
First, the metal is machined to make it closer to the shape of a final product. You might think it’s ‘nothing but pliers’. We drilled a small eye to fix the pliers. This is very important, a little difference will affect the coordination of the entire pliers. We make proper adjustments of individual machines, committing ourselves to making only the highest-quality products.
Rough scraping
Producing roughly form a metal casting into the shape of a plier via machine.
Forming
Gradually have the appearance of pliers.
Fine scraping
Scraping the pliers further to make it more refined.
Assembly
After combining the right and left parts by inserting a pin, the operator manually makes adjustments. For the first time, the metal is formed into a pair of pliers. In this process, the left and right parts, sent separately from the machining process, are assembled into a single item. Since this process is the groundwork for the post-process, the operator checks each pair of pliers, individually, to make sure there is absolutely zero mis-alignment when the left and right parts are assembled, making delicate adjustments, if necessary.
Crating blade
Crating a blade from the original metal casting head according to the technical specifications.
Precise drilling
Drill a considerable eye so that the rivet can be stamped.
Riveting
Stamping rivets make the pliers firm and stable.
Grinding
Grinding the surface of the pliers with a grinding wheel.
Quencing
After quenching the entire part, the operator applies high-frequency induction quenching to increase the hardness of the tips. The operator applies quenching equally to the left and right blades to increase the hardness, in order to produce highly durable blades of equal hardness. However, if the metal is too hard, it becomes rather brittle. Therefore, we check the products with rigorous standards, by conducting tests on body hardness, blade hardness and impact resistance.
Blade sharpening
If the edges of right and left blades hit each other accurately, their durability becomes inferior, while if they overlapp too much, the sharpness becomes inferior. This process decides the cutting sharpness, which is the most important for all types of pliers. We cut using the bottom ends of the blades, in the case of side cutting pliers, while we cut using the top ends of the blades, in the case of nippers. Therefore, the operator manually sharpens the edges of blades, one by one, by thinking about how to use products.
Polishing
In this finishing process, workers will polish products carefully. This process will not affect the function of the product. However, if a product has a poor appearance, customers will not pick them up from the shop counter. Therefore, we carefully polish our products by paying full attention to appearance, including the balance between the left and right parts, uniformity among each product and offer beautifully polished surfaces.
Cleaning
Use ultrasonic cleaning pliers to have a clean surface.
Quality inspection
When products go through the production processes, individual parts sometimes have various delicate misalignments. The operator carefully makes manual adjustments to correct such delicate misalignment to produce the high-quality products of the WAIT® brand.
