Recycled Rubber and PU Tire Filling Solution
Haifeng integrates recycled rubber granule and PU tire filling with metered feeding, mixing, pressure control and curing for off-road tire casings.
Recycled Rubber & PU Tire Filling Solution
Blend selected recycled rubber granules with a polyurethane filling system and pump the composite into an existing rubber tire casing. Coordinate liquid metering, independent granule feeding, blending and the discharge path as one filling process. Granule fraction, size distribution, cleanliness and moisture are specification inputs rather than fixed universal values.
Dedicated Cavity-Filling Route
Use the existing casing as the filling envelope. Do not apply high-pressure closed-mold tire-casting settings to this route.
Define the Assembly and Formulation
State tire and rim identity, load and speed conditions, formulation, ratio basis, material quantity and cure criteria in the technical specification.
Haifeng coordinates material delivery, the filling connection, controls and curing-workflow integration for the specified order. Delivery includes on-site commissioning, operator training, a 1-year machine warranty and long-term spare parts support.
From Material Preparation to the Cured Tire Assembly
Four coordinated stages for the selected tire, formulation and equipment configuration.
Material and Tire Preparation
Select a compatible granule grade and PU system, and assess the existing tire casing, rim and filling connection. Establish the recipe and the records needed for the order.
Coordinated Feeding
Meter the two liquid components to the formulation requirement and control the granule feed independently. Specify a mixer and discharge path suitable for the selected particle grade.
Composite Tire Filling
Blend the liquid components and granules before introducing the mixture into the existing tire cavity. Manage filling and air release with tire-specific pressure control.
Equipment Reference and Application Inputs
Existing Haifeng equipment data are stated separately from tire-specific process settings.

Reference Haifeng Tire-Filling Equipment
Review the current equipment configuration, then define the application-specific filling integration.
Configuration Priorities
Define each control function around the tire and formulation.
Metering and Recipe Control
Specify the liquid components and ratio basis independently of any granule feed.
Separate Pressure Settings
Define the tire-cavity setpoint and the equipment operating limits separately.
Coordinated Filling Integration
Match the mixing, material path and filling connection to the liquid or particulate mixture.
Batch and Release Records
Record material batches, filled quantity, pressure and cure-release checks for each order.
Tire-Filling Questions
Key differences between tire filling and complete tire molding.
Is this the same process as molding a solid PU tire?
Can the pump working-pressure range be used as the tire filling pressure?
Is there one cure time for all PU filling formulations?
Does the filling machine give the tire a 12-ton load rating?
