Computer numerical control is the process of controlling machining tools like drills and lathes using a computer. The material that may be a composite, plastic, or wood piece is subjected to the programmed instructions
Types of Wood Calibration & Finishing
Many concerns assess wood calibration on a regular basis. The huge economies of scale limit the number of samples that can be analysed.
Pre-Press Technique for Manufacturing Plywood
We pre-press to compress the material before it enters the main hot press. So, this is an important process in the making of plywood.
The Laminate Cutting Machines: The Appropriate Size for The Purpose
Making laminates is an essential part of woodworking. The idea is to protect the surface of the workpiece by providing a hard, impervious surface. Thus, the laminate is a man-made object, unlike veneers that are from natural wood. Laminates are usually of plastic. We use phenolic and melamine resins to make Sunmica sheets.
Materials used in the lamination process
To use the laminates, you have to cut them to size. We use the Laminate cutting machines of the appropriate size for the purpose. To make the laminates we use papers soaked in the appropriate chemical resins to make them stiff and strong.
The main ingredients used are as listed below:
- Phenolic resin
- Brown paper
- Clear translucent paper
- Melamine resin
You also need a variety of machines. These would include the following:
- Drying and cooling machines
- Paper impregnation line
- Hydraulic press
- Cutting machines
- Sanding machines
- Steel plates
Manufacture of laminates
Soak the resin: This is the first step. Use phenolic resin to soak the brown paper. We call the soaking process impregnation because the brown paper gets soaked in the resin. The machinery we use for this is the Paper impregnation line. The resin makes the surfaces hard and stiff. So, it resists wear and tear and all kinds of scratches.
Dry the papers: This follows the soaking process. Once complete drying is over, we go to the next step. Now the paper which we could tear with ease is hard and tough.
Cutting the paper: We now cut the stiffened paper to the needed size. Cutting machines (called cutters) cut the laminate sheets to 8×4 feet size. This is the common dimension.
Applying high pressure for bonding: The papers get pressed together under high pressure. High temperature gets applied with the brown paper forming the bottom layer. The top layer is a clear translucent paper. We keep all the needed laminates together, one on top of the other and pressed. We use steel separator plates so that the laminates do not stick together. Now, it is customary to use designs on the plates. These patterns get transferred to the paper. Pressing is one of the most important processes and the pressure application helps develop more patterns as needed.
Sanding the unused part: The obverse side gets sanded. This is the non-decorative part which gets sanded in a uniform way. Carpenters use Fevicol or other glues on the sanded part while attaching Sunmica sheets.
Final steps of the process
We use the Laminate cutting machines in the latter stages for resizing the laminates. If this is not needed, the sheets are ready to get packed as they are. The thickness of the laminates ranges between 0.6 mm and 1.5 mm. You can get laminates with a greater thickness between 3-25 mm and these we call compacted laminate sheets.
To cut your laminate, score the edges of the laminate with a knife. Use a circular saw to cut into one side (about ¼ inch) of the laminate. This helps prevent tear-out. Now, do the same for the other side and watch out for the kickback.
Uses of Woodworking Veneer Pressing Machines
A veneer is the real surface of a tree that we peel and use to make furniture and other wooden objects. It is susceptible to scratches like real wood but because it has the qualities of real wood
3D Engraving Wood Working Machines & Others
The laser engraving machine has three main parts – a laser source, a surface, and a controller. The pencil-like laser is under control of the controller and they combine to trace patterns on the surface.
Types of Shutters and Shutter Making Machines
Modern houses are attractive for many reasons. The reason is that they are laid out in a functional manner, each work integrating with the next seamlessly. Another major reason is that they use the latest frames and shutter having superior strength and appearance. We have more than one kitchen shutters. We use various types of machines to make them, the membrane kitchen shutter machines are used to make membrane shutters for the kitchen. Shutters are classified into interior materials and exterior finish type. Here is a look at the various kitchen shutter types.
Natural wood shutters for kitchens
Rubberwood, oak, teak, and walnut find use as interior shutters. The outer side is polished with waterproof material. They are not an eco-friendly option and they are expensive. But, you get a highly aesthetic appearance.
Post formed shutters
Decorative laminates like mica sheets are pressed on the particle boards and plywood using high pressure. There is no need to produce edge banding for this type of shutters.
Veneered kitchen shutters
You can get a natural wood finish for your kitchen shutters using wood made from veneers of natural wood. They are glued to plywood boards and have the natural look of wood. Patterns are made to resemble walnut, teak wood, and oak wood.
Decorative laminated shutters
Laminated wood is applied on MDF boards or plywood. We use PVC tape to band the edges. They have sharp edges that can cause damage.
PVC membrane laminated shutters
Here PVC membranes are applied to particle boards or plywood. Membrane kitchen shutter machines help you make these boards with ease.
Shutter making machines
Shutter making machines are of three types – Strip forming machine, Guide forming machine, and bottom forming machine.
Strip forming machines: These come with preformed rolls and the desired strip is formed in one pass. These are best suited for making rolling shutters. The machine is high speed and low maintenance. It is highly durable and comes in various sizes. It is driven by electricity. It has great strength and is easy to operate.
Bottom forming machines: This is used to form heavy floor deck of many types. It is cold roll forming with working speeds of 3-13 m/minute. It has a hydraulic type decoiler with two roller feeding, with wallboard type leveling machine. It has an individual memorial arch type structure. It uses a universal drive shaft between the shafts and uses a common motor and frequency converter to control the speeds.
Guide forming machines: These form specific configurations from long strips of metal and in most instances the specific cross-section is designed specifically for the machine so we can bend the metal as needed. Other than this, we can use the machine to do a variety of things such as roll punching and metal cutting.
It is important to have a high-quality woodworking machine to get superior products. Whatever is the material you choose, one must only take care to see that they belong to the interior or exterior type. This will allow you to use them for a long time without any damage. Use of quality components gives you industry standard shutters that last a lifetime.
A Few Things to Know about Plywood Cold Press Machines
A plywood cold press machine is also referred to as a pre-press machine. It is basically an auxiliary machine as far as the plywood production line is concerned. Its main purpose is to reduce the cycle time that is needed in case of hot press and thus make the plywood better in terms of quality before it gets glued. It can also be said that a cold press machine belongs to the pressing machine. These machines are also used in order to press the gluing veneer. This makes sure that the gluing veneer is in proper shape. After this the plywood machine is put into the hot press machine so that it can be pressed again.

A Few Things to Know About Post Forming & Edge Banding
When it comes to the interiors of your home one of the main things that you are thinking about is post forming vs edge banding. The term post forming basically means something that has been formed after it has been laminated. This lamination can happen on plywood or any other substrate for that matter. Post forming is basically a process where laminates are applied on a surface such as plywood or MDF (Medium Density Fibreboard). In fact, post forming can be done on any surface that has edges that are specially formed. After this, the laminate can be rolled over the edges.
The purpose of post forming:
This is done in order to create a laminate that is single and unbroken. In these cases, the post formed edges are not sharp at all. In fact, they have a nice and rounded finish. Normally, the companies that manufacture such products press the laminates in a manual manner. They normally take the plywood pieces to the factories so that they can be post formed. The thing with a post formed finish is that it costs a bit more than what a regular finish would cost you. In these cases, normally the laminate is bent so that the post formed surface can be created.
Edge banding:
Normally, when plywood is cut it has a raw edge of sorts. If you do not cover the raw edge it will look bad at the very least. Apart from that it would also lead to scratches. This way, there is also a good chance that moisture can seep in the plywood and this would make the plywood lumpy or warp. In these cases, the raw edges are normally covered by using edge band, which is basically a narrow strip of material.
Some more information in this regard:
The thickness of this edge band is normally 0.5 mm at the least and 2 mm at the most. Of course, you should expect some variation in the prices. Normally the price of the thickest bands, the ones with a thickness of 2 mm, is around 3 to 4 times higher than the thinnest ones, which have a thickness of 0.5 mm. In fact, Wikipedia says that the term edge band denotes the process used to cover the aforementioned edges. As has been implied already, the main purpose here is to make sure that the edges of the laminate ply look good and are durable as well.
Normally, if you post form the laminate you do not need to use this. It is used to cover the edges that have not been post formed.This gives the laminate an appearance that is better from an overall point of view.
The different kinds of edge banding:
There are many 3 types of edge banding. These are manual, semi manual, and through fit. As the name would suggest, in case the edge band is pressed in a manual way over the edges. This normally happens when the work is being done onsite.
