All products are manufactured in accordance with international standards. The extrusion die, aluminum billet, extrusion profile, coating process are all carried out at YKK AP Indonesia manufacturing plant.
The raw material aluminum bullion is put into the melting furnace and melted. After degassing, it is poured into a circular mold and cooled in a pool to produce a cylindrical ingot "billet". The finished billet is heat-treated in a continuous homogeneous furnace. The metal structure is then homogenized for ease of extrusion in the next "extrusion" process.
We manufacture in-house dies that require precision. With Highly skilled die engineers made possible to produce high quality aluminum profiles.
Heat the billet and set it in the extruder. By pressing it against the mold with high pressure, an aluminum profile is extruded.
Aluminum profile quality is managed under strict quality control process, with strict dimensional deviation and quality checks are conducted before proceeding to the next process.
Corrosion resistance and wear resistance are improved by alumite treatment that forms a film on the surface, and coloring and painting are performed. Anodizing is our innovative surface treatment. The advantage is increased resistance to corrosion from chemicals, longer glossiness and protection against weather effects.
Painting (Powder Coating)
Our powder coating process is designed to meet the AAMA (American Architectural Manufacturers Association) standard. By doing the pre-treatment process before powder coating, the product is made more corrosion resistant.
After surface treatment is done, aluminum profiles are fabricated with plenty of experiences and skills. It ensures our product quality.
Proof of Performance
In-house testing are conducted based on YKK AP high technology.
Performance tests are based on AAMA, ASTM, JIS, SNI. By conducting the test, we are able to supply high-quality products.
