  Company Information Shandong Senmao Machinery co.,ltd.  is a professional and high-tech enterprise which is specialized in manufacturing wood working machinery and equipment and which integrates research and development, manufacture and sales. The company has developed many featured design machine and already get the State Patent.   Your satisfaction is our eternal pursuit !   Plywood Production machinery Plywood processing technology: In the producing process, log cutting, peeling, dry, handling, hot press, edge trimming, sanding affect the wastage. The wastage is remains of processing (materiality) and shrinking (immateriality). Wood wastage is related to the material, specification of log, equipment capability, technology and production specification.   1) Log cutting: Usually import log length is more than 6 meters. Cutting according to the technology required length and quality. The cutting length should be product length add remains. For example, product is 1220mm*2440mm, cutting length usually be 2600mm or 1300mm. log length, camber and demerit affect plywood output directly. Remains are small wood pieces, truncations, sawdust, tec. Log cutting wastage ratio is 3%-10%.     2) Veneer peeling:   Peeling is the basic processing the wood from log to the plywood. Before peeling, the lod always need be debark and rounded .there are always two kinds of veneer : core veneer and face veneer. core veneer is thicker and samller . the size always be 1300*850mm, and thickness always be 1.5mm to 3.0mm .and face veneer is thinner and big, the common size is 2700-1250/1270mm, the thickness is alway be 0.15mm to 0.6mm.       3) Drying:   Veneer is moist. it should be dried according to the technology requirement. After drying, it will shrink. Dimension will become smaller. Veneer length, width, thickness will shrink.  Shrink wastage is related to wood material, moisture containing, veneer thickness. Shrink wastage is 4%-10%.    4) Veneer handling:   Handling include cutting, putting veneer together and mending. Cut zonal veneer into specification veneer or proper size which can be put together. Narrow zonal veneer can be put together into one veneer. Veneer with demerit can be mended to be qualified. Wastage in this part related to log material, peeled veneer quality, dried quality, and worker operation skill. Wastage ratio is 4%-16%. Import veneer processing plywood wastage ratio is 2%-11%. 5) Veneer gluing  After the veneer handing , the veneer must be gluing before use. Now, the most popular gluing method is double sides glue for the core veneer.   6) the core veneer composer    After the core veneer glued, the worker will compose the core venner with some certain sructure. In this procedure, a core veneer compose machien will help you make this job easier and more efficency.    7) cold  press: After the compose, the material will be send to the cold press by lifter. After several hours, the materil will be formed preliminary.   5) Hot press:   In order to make the glue fully effective, the basebaord should be send to dealt by some certain temperature and pressure . In this stage,the hot press is necessary. When the temperature and pressure increased, the veneer moisture  changes, veneer will shrink.  Shrink wastage is related to temperature, pressure, hot press time, wood material, moisture containing, wastage ratio is 3%-8%. And when laminate the face veneer , hot press is also needed.   6) Edge trimming:   Trimming the edge of the plywood flank from hot press to qualified plywood board. Remains related to process remains and product dimension. Production is bigger, wastage is smaller. Wastage ratio is 6%-9%   7) Sanding:   Sanding is makes the plywood surface smooth and calibrated. After sanded, the surface will be suitable for veneer and  decorated paper. Wastage is powder. Veneer quality is good, sanding is less. Wastage ratio is 2%-6%   8) Warehousing:   Plywood after sanding, the worker need to inspect, and classfied , then packed and g in pallet or in bulk.   Our Services   1.We will send our engineer under your indications to  your  factory  for  installing,  debugging  and  maintaining,  you only need to afford the cost of the flights, and  the engineer's accommodation .   2.If you are experienced in installing jobs,  we  will  provide ongoing  technical support for you. Guarantee time for the main parts of the machine will be 12 months, in this period, if the machines itself  have the problem, we will freely maintain it, but not including the problem caused by the wrong or rough operation.   3.The buyer sends people to seller’s factory for study: one month and one person. The buyer should pay for the round air fare, and the seller arrange for food and accommodation, and the service including: the machine’s fixing, debugging, operating, maintaining.   4.After the warranty, we can also supply the engineer service and the technical service, but  you need to  pay  the salary for the engineer! and afford the cost of the replaced aparts yourself. More service, you can get by send us an e-mail or a fax, or you call the number 0086-15866993298  for instructuion directly.       FAQ   1.
