VOC and worker exposure
Volatile solvents can require local extraction, enclosed handling, exposure monitoring and off-gas treatment.
A different forming route
One-piece injection-compression molding for isolator gloves.
Kingsure forms the complete glove from solid rubber compound inside dedicated closed tooling. The route removes the repeated open-bath coating step and sharply reduces reliance on the solvent preparation systems used by solvent-based dipping processes.
Technology leadership
Moving isolator gloves beyond the conventional dipping model.
Kingsure is the world’s first manufacturer to apply one-piece injection-compression molding to the scaled production of dry-box rubber gloves, replacing repeated liquid-bath film building with solid compound and dedicated closed tooling.
Two forming routes
Open-bath layer building versus closed-mold forming.
R&D background
Why Kingsure challenged solvent-based dipping.
Solvent is not only a formulation ingredient. Once introduced at scale, it creates an entire control system around storage, mixing, ventilation, fire safety, emissions and waste handling.
Fire and storage controls
Flammable liquids add requirements for classified storage, transfer, grounding, ignition control and emergency response.
Cleaning and waste streams
Tank changeovers, residue and cleaning materials create additional solvent-bearing waste that must be controlled.
Many interacting variables
Bath viscosity, solids, former temperature, withdrawal speed, ambient conditions and drying all affect the deposited film.
Engineering objective
Kingsure’s objective was not to call a conventional line “greener,” but to remove the repeated liquid-bath forming mechanism itself and rebuild the process around solid compound and closed tooling.
Controlled manufacturing sequence
From compound verification to finished-glove release.
Control is concentrated on compound condition, tooling, injection-compression parameters, curing, demolding and documented batch verification.
01
Compound preparation
The rubber formulation is mixed, conditioned and verified before forming.
02
Tool preparation
Cavity condition, cleanliness and critical tooling surfaces are confirmed.
03
Injection-compression forming
Compound fills the closed cavity under controlled pressure and temperature.
04
Curing
Time and thermal history are managed to develop the required properties.
05
Demolding and finishing
The continuous glove is removed, finished and visually examined.
06
Batch inspection and release
Representative samples from every production batch are tested and recorded before release.
Designed into the mold
Geometry, thickness and reinforcement become engineering variables.
In a dipping process, film build is strongly influenced by liquid behavior and repeated coating conditions. In Kingsure’s route, the dedicated cavity defines the principal glove geometry, while controlled material charge and molding parameters support repeatability.
- One continuous hand, finger, sleeve and cuff structure
- Targeted reinforcement can be built into defined high-stress zones
- Critical dimensions and nominal thickness are verified against documented criteria
- Mold, batch, process and inspection records support traceability
