Logs arrive on site by
truck to be processed at the chipmill. Two rotary cranes and a 27
metre drum debarker handle more than 300 tonnes of logs per hour.
Woodchips are broken down
into their natural cellulose fibres and resin and wax is added.
The dried fibres are formed into mats and processed through presses.
The use of continuous press technology, pioneered by Nelson Pine
Industries in the Southern Hemisphere has been a key factor in securing
the high reputation and dominant market position of the GoldenEdge
product.
Advanced technology sanders
put a quality surface on the finished board before it is sawn to
a range of sizes to meet various market niches.
Research carried out in
conjunction with resin suppliers, has enabled us to reduce the formaldehyde
levels in our Medium Density Fibreboard to the point where all GoldenEdge
product is marketed with low fuming formaldehyde emissions., down
to E.O Recent developments have enabled NPI to produce a full range
of thickness to meet the new Japanese F**** standard which is the
lowest emission standard in the world.
Hard work in our laboratories
is paying off in the development of moisture resistant product.
The challenge is to produce board with low thickness swelling levels
in all climates, including the very humid conditions experienced
in some of our market destinations. By tailoring the type and level
of resin we are achieving thickness swelling levels well below industry
standards.

New Zealand's exotic Radiata
pine forests provide a quality of fibre uniquely suited to the production
of Medium Density Fibreboard. Logs arrive on site from the forests
and leave as a range of MDF products tailored to market needs worldwide.
Added Value: A further processing facility converts panels into
moulded products used as an alternative to dressing grade timber
in the building and furniture industry. These moisture resistant
mouldings are exported to all our main markets.
The Research and Development
programme aims to improve the quality of product to meet and anticipate
market demands, with a focus on:
- Low formaldehyde emissions
- Lightweight MDF
- Moisture resistance
