Product Overview
Specially designed for precision pouring of medical polyurethane sponge, stably producing wound dressings, medical pads, hemostatic sponges and other medical consumables.
This low-pressure PU dispensing machine can be evaluated for sponge formulations intended for medical applications. Metering, mixing, temperature control and cleaning arrangements are selected around the material and production brief. Medical-use suitability, biocompatibility, contamination control and sterilization require separate validation of the formulation, finished device and manufacturing process. Equipment supply does not establish a sterile production environment or medical-product approval.
Operation Workflow
Material Preparation
Select the formulation and establish controlled handling and cleaning procedures for the intended sponge application.
Temperature and Recipe Setting
Confirm the material temperatures, tank arrangement and mixing ratio with the formulation supplier.
Metering and Mixing Trials
Verify dispensing repeatability and mixing quality on the selected formulation and operating range.
Molding and Finished-Part Validation
Mold representative specimens and validate absorption, contamination control and any intended medical-use requirements separately.
