Fabrication Guidelines

Rotational Molding & Lining Procedures

To ensure a dense, void-free, and homogeneous lining layer, adhere to the following rotational processing controls.

STEP 01

Mold & Substrate Preparation

Equipment and metallic molds must withstand high temperatures and thermal shock. Internal surfaces must be thoroughly cleaned and prepped to ensure proper cladding adherence.

STEP 02

Powder Charging & Venting

Charge neat Everflon™ PFA GS40 resin evenly inside the hollow structure. Dedicated vent tubes must be installed on all molds to prevent internal pressure buildup.

STEP 03

Biaxial Rotation & Fusion

Rotate biaxially and heat above the melting point. Controlled melt flow ensures the resin distributes evenly and builds up smoothly along complex internal contours.

STEP 04

Controlled Cooling & Disassembly

Regulated cooling causes the molten resin to solidify and densify into an integral lining. Hot molds must be disassembled exclusively in well-ventilated areas.

Handling & Logistics

Packaging, Storage & Handling

Preserving purity and stable resin properties throughout the logistics lifecycle.
