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.wire veneer drying machine

hot press cold press glue spreader glue mixer_副本veneer peeling lathe

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.
