Hardwood is our basic raw material for manufacturing best quality plywood. We are importing timber (GURJAN species) at present from Burma. These logs are carefully selected by our most experienced personnel to achieve the best quality of the final product. After receiving the timber it is stacked in the timber yard after which, serial numbers are given to each log. The logs are then cut as per requirement and again part serial numbers are given to each log (cut piece). Then the logs are moved into the Log pond.

Quality Control in manufacturing process:

Generally the logs are kept in the Log pond for a minimum of 7 to 10 days for better ponding. Then as per the requirement it will be kept in boiling vats for 1-2 days. After cleaning through the air pressure or water only boiled timber comes to the peeler from the boiling vats. We peel the logs in various thicknesses of core and face by using the latest technology. Peeled Veneers are then reeled on to the reeling machine. We then cut the core and face veneers through a clipper according to the required sizes. While clipping we purposely tend to avoid cracks, knots, open holes, fiber and variation portions to get the best quality of raw material that would be processed further. Then the veneer is sent to the dryer machine. Here, moisture should be kept 6 to 8% in core veneers and 10 to12% in face veneers. These are the international moisture standards which would ensure good binding. Dried veneers are then sorted by skilled workers. Core & face veneers are properly bundled and sent to the warehouse.

Glue:(resin) 

For manufacturing best quality plywood we are also manufacturing Resin (Glue) at our premises. We are manufacturing both UF and PF Resin:-

All the raw materials (core, face & glue) are issued centrally to the pressing department for plywood making. Here, a few necessary extenders like Melamine, GNCP, CSP Corn Powder, Borax Chemical etc. are added into the UF or PF Resin as per our formula in the glue mixer machine.

Then gluing of the core veneer is done by the glue spreader machine. Core veneer used for PF plywood is stacked for 24 hours after the gluing process for better bonding. Then the core veneer and face veneers are assembled in accordance to preset guidelines and pressed in hot press applying the required pressure at high temperatures. We have a 10 daylight hydraulic press capacity of 630 Ton.

Then the Pressed sheet of plywood is sent at the D.D Saw machine for side horizontal and vertical trimming. Then the plywood sheet is sent to a sanding machine. PF Plywood sheets are dipped in CCP solution before sanding as it would protect the plywood from BORER TERMITE and FUNGUS. After this the plywood sheet is sent to the finishing department.

Quality Control Measures:

At TOPL rigorous guidelines in quality control are followed throughout the manufacturing process, to bring out the best quality. At each and every stage of the production cycle, the work is carefully monitored. Experienced and skilled workers repair and eliminate imperfections. These controls enable us to consistently produce high quality products.

Quality Control in purchasing Raw material:

Timber: Timber is the basic raw material for plywood. We are using only hardwood species like GURJAN for making both commercial & BWP plywood. At present we are importing the GURJAN Timber from BURMA to manufacture core and face veneers.
