Plywood for outdoor use
exterior type
plywood
Plywood made of phenolic resin glue or resin with the same performance as the adhesive has the properties of weather resistance, water resistance and high humidity resistance, and is suitable for outdoor use.
Structural plywood
structural plywood
Plywood can be used as a load-bearing structural member of a building.
Plywood for concrete formwork
plywood for
concrete-form

grain plywood
long-grain plywood
Plywood with the wood grain direction of the surface parallel or approximately parallel to the length of the board.
Striped plywood
cross-grain plywood
Plywood with wood grain direction parallel or approximately parallel to the width of the board.
multi-layer plywood
multi-plywood
Plywood made from five or more layers of veneer blanks.
Formed plywood
moulded plywood
It is a non-planar plywood made of glue-coated veneers to form slabs according to certain requirements and hot-pressed in a mold of a specific shape.
Mitered plywood
scarf joint plywood
The end of the plywood in the direction of the grain is processed into an inclined plane, and the long plywood is lapped and connected by gluing.
finger joint plywood
finger joint plywood
The end of the plywood in the direction of the grain is processed into a finger-shaped tenon, and the long plywood is connected by gluing and finger-joining.
Hello friends, i am Lucinda, the sales manager of SHANDONG MINGHUNG WOOD MACHINERY CO.,LTD, our factory produce the whole production line of plywood machine, like the wood veneer peeling machine, veneer dryer, hot press machine, cold press, and other plywood machine.
i think most friends have felt the influence by the covid-19. especially the export business.
for us, we export the plywood machine to kinds of countries.
the shipping cost rise so high, many shipping workers have done this business many years, and this is the first time they met too. and at the same time, lack of containers.
recently we ready to delivery the veneer production line includes wood debarker, veneer peeling machine, log transporter, vacuum veneer stacker, and magnetic knife grinder to Turkey, we have contacted at least five shipping agent, let them order the container, but it is still difficult. at the same time, China material price rise high also, and keep rising. this result plywood machine price increase higher too. especially the hot press, becuase it is very heavy, use much steel material.
this is a tough trading environment, it is not easy.
BUT, we believe it will become better, it must.
nothing can stop the business trading of each country.
in this time, we will continue to make our plywood machine better and better, focus on each details, choose the good parts, make our machine strong and good. like our tombuk soyma makinasi, it has been very strong, to produce very nice wood veneer.
we insist offer the good and strong plywood machine and veneer machine to our clients, help their business become better, help them create much benefits and values, this can achive win-win.
