Production & Manufacturing
All key process under our own control
Compounding
With strong background of research and development radiation modified polymer materials, we are producing and developing varieties of chemical formulations for different heat shrinkable products. Advanced mixing facilities ensure the fine dispersion of components in each formulation and the homogeneously physical, electrical and chemical properties in final products.
Extrusion & injection
To obtain the products with stable and homogeneous dimensions, we equipped with more than 40 advanced extrusion line in which many key parts were improved by technology from foreign countries. Extrusion is used to make the masterbatch to run through the feed section, the plasticized section, the melt segment, and add pressure to make the material to flow continuously through the special design extrusion die and then cooling device to shape into a predetermined design.
Radiation crosslinking
The specially designed advanced under beam facilities can be easily adjusted to meet the requirements of different size and shaped products and ensure the homogeneous crosslinking of products. The material is exposed to high energy penetrating radiation which causes a bonding of the various adjacent molecular chairs. The process of forming the bond is “crosslinking” and it results in the transformation of plastic structure into new three dimensional network.
Expansion
Expansion is a very important and key process to obtain the final forms and dimensions of heat shrinkable products. We can accurately control the dimensions, longitudinal changes and eccentricity of the final products.
Packing & storage
Packing according to customer’s needs Sorting product out into categories and keeping it in a humidity controlled environment (-10 ℃ to 40 ℃ and ＜ 75% relative humidity)
