Swedish Tapping And Riveting
Sheet metal fabricated products are assembled by joining variously processed parts. Joining methods in this case include welding, gluing, riveting, screwing, folding, etc.
We can provide various fasteners and processing methods according to the needs of our customers. The full utilization of China’s rich fastener market is an important advantage of our cooperation with European and American designers and engineers.
Tapping
Tapping is the process of cutting thread into pilot holes drilled by presses, punching machines, laser processing machines, drill presses, etc.Tapping done by hand is a simple task but it makes difficult to maintain concentration, resulting in forgetting to tap or tapping defects.For this reason, tapping is now being automated.
Tapping Inspection Method
The accuracy of tapping is inspected by using Go/no-go gauge to check the effective diameter and inner diameter of the female thread.
A Go/no-go gauge is a combination of a gauge that must pass (go side) and a gauge that must not pass (no go side) and verifies that the dimension of the object to be measured is between them.
Used to inspect the effective diameter of a thread. The longer side is the GO side, and the shorter side is the NO GO side.
The GO side is used to check that the entire length of the female thread can be threaded in comfortably by hand.
The NO GO side is used to check that the gauge cannot be threaded in more than two turns from either side of the machined thread.
Depending on the manufacturer, this may be called a fastener, insert, crimping, or clinching, but it is used in a construction method in which special male and female screws are pressed into sheet metal.
The fastener is inserted into a pilot hole drilled in the sheet metal, and press machine is applied to press the fastener into the pilot hole, causing the sheet metal to deform and the fastener is fixed by biting into the fastener groove.
Anyone can use it easily, and it can be used on a variety of sheet metals, including steel, stainless steel, and aluminum.

Weld studs are an excellent alternative to screws and self-locking fasteners; they can be made from iron, copper, stainless steel, aluminum and brass and can be welded to any type of metal plate (iron, aluminum, stainless steel and brass). They can be used to create very durable fasteners without having to make holes in the plate.
But please note that when installed on metal plates with a thickness of less than 3mm, there may be slight welding marks on the back of the metal plate.
Welding nuts are commonly used for welding products with a thickness of more than 3mm. When it comes into contact with the material of the workpiece, the contact point of the nut is fused with the workpiece to form a permanent connection through pressure without filling material.
The advantage is that the welding strength is relatively high and the application range is wide. It could be used on thin and thick materials. However, due to high temperature, the connected metal sheet will deform and the nut cannot be disassembled. When it has to be removed, the thin plate will become unqualified due to deformation after removed.
