Pulp-Injection
Injection Molded Pulp – Achieving Precision, Thinness, and Rigidity
- Environmentally friendly injection molded products made from pulp and starch
- Extensive design freedom in shape achieved through molding process – Feasible boss, rib, and flange shape
- Precise, thin and rigid material property
- Premium paper texture
- Recyclable as paper*
*Depending on the regulations and guidelines of each country or region.
Process
- Specialized pellets made from pulp and starch as the main ingredient.
- The process involves mixing pellets with water and injecting the mixture into the mold.
- The mixture is heated to remove moisture in the mold.
- After molding, the products are trimmed to remove excess material and eliminate any burrs.
Key Features
- Thin and high rigidity
- Despite being thin with a thickness of around 1mm, it possesses strength equivalent to that of plastic, providing protection for the product against impacts during transportation.
- Premium paper texture
- The surface has a texture reminiscent of traditional Japanese paper, exhibiting minimal paper dust and a clean look.
- Extensive design freedom in shape
- Equivalent moldability to injection molded plastic, allowing for functional and versatile designs with the addition of ribs and flanges.
