Ten types of common wood mortise and tenon type!

In the whole wood household products manufacturing process, it is inevitable to use a variety of mortise and tenon methods. This paper tries to show a variety of ways as comprehensively as possible to help readers further optimize the quality and processing efficiency of their products!!


In order to further improve the process added value and quality firmness of products, many whole wood enterprises have introduced a simple combination of solid wood furniture structure.


The connection of wood parts is a process of combination between parts. This process is a simple and complex process. The splicing process can be understood as a process of mutual contact and occlusion!


First of all, look at the connection between the strip components, mainly including direct, plug-in, overlapping and other forms!

The above mortise and tenon structure looks simple, but it contains too much wisdom and technology. I believe that you should have seen most of the link forms shown above. Next, I will organize the more common mortise and tenon methods in the market into ten categories, hoping to help you!


Type I, single tenon type plug-in type

Most of the components are connected by mortise or similar mortise, which is a common way of connection with low processing requirements.

Type II, double tenon type plug-in type

In order to increase the contact area between the structures, the double tenon is used for some parts which need to be stressed. The fabrication of this kind of structure is a little tedious, but the strength is better.

The third type is the overlapping type

Component cross processing often occurs in the place where the structure meets. In order to increase the relevance between components, the connection processing method of overlapping and occlusion will be adopted.

The fourth type is accessory type auxiliary type

It is easy to process and simple to assemble through the auxiliary connection of wooden cake, wooden pin and other accessories, which is a common part connection mode.

The fifth type is the panel type plug-in type

The interconnection of plate-shaped components needs to use this kind of connection mode, which is a common connection mode and is easy to manufacture.

Category VI, dovetail plug type

This kind of connection is often used in the drawer, which is the conversion of the traditional mortise and mortise connection. The equipment is easy to use.

The seventh type of lock catch

This kind of connection mode mostly appears in the manual manufacturing, the relative processing requirements are relatively fine, and the structure of the products produced has a better stress.

Type 8, finger type plug-in type

Finger joint is a common way of wood plate connection, and some of them will be used for plate material connection, which needs to be made with professional cutters.

Type 9, interpenetrating butt joint type

This kind of plate butt joint with pin through style is seldom used, which requires fine workmanship and symmetrical splicing, but the tenon joint effect is better.

Type 10, swallow tail extension

It is a typical modern mortise and tenon connection mode. The form of dovetail tenon is widely used, which is not only convenient for processing, but also beautiful and generous.

Due to the space problem, only part of the structure is shown here. If you want to get more friends, please read on!

Good connection mode depends on good processing equipment to achieve, and the relative price of fast and good large-scale numerical control equipment is relatively expensive, so many enterprises can only stop. Let’s take a look at some small and medium-sized woodworking equipment, they can also meet the “fast and good” processing needs.

Electric dovetail joint machine


The electric jointing machine adopts fully automatic pneumatic pressing and slotting to complete one step, forming two dovetail grooves at one time. With high accuracy, simple operation, time-saving and high power, it can comprehensively improve production efficiency.

It is a necessary tool for the door and window industry to use the formed dovetail milling cutter to finish one-time processing and butterfly connecting block to connect two workpieces of 0-90 degrees. The machine is suitable for connecting picture frame, mirror frame, stair handrail, furniture component, drawer, cabinet, door frame, etc.

Transverse dovetail slotting machine


The machine is suitable for connecting picture frame, mirror frame, stair handrail, furniture parts, drawer, cabinet, door frame, etc. in the processing process, it needs to assemble and disassemble the frame for many times, and can keep the wood frame from being damaged and convenient for after-sale disassembly. The operation is simple, time-saving and efficient, bringing the best convenience for transportation
