FibreTuff PAPC Micro Molding

Micro molding Accumold part

FibreTuff Micro Molding

Creating new micro molding devices with PAPC and lowering costs

Replacing existing biomaterials

• Devices needing bio absorbable qualities.

• Not re sorbable in the human body.

• Devices requiring Standard Sterilization methods.

• Sensitive tooling constraints - long production runs.

Cost Benefits

• Specific Gravity is 20 to 30% less

• Doesn’t require specialized packaging.

• Not very hygroscopic at 10-30% cellulose

• No Extensive drying - at 20% cellulose with high heat polymer .21% Test method

ISO 62 24 hr. immersion.

Process validation of PAPC

• Sodick injection system is good for FiberTuff material evaluation per Kohei Shinohara.

• Sodick utilizes a proprietary two-stage V-LINE method for plasticizing and injection


• Both 14mm screw and 18mm screw were used to mold. The feeding is better on the

18mm screw but both small screw treat the raw material of FiberTuff biopolymers.

• The process was very stable and the parameters were consistent.
