PU Safety Shoe Production Solution
Haifeng plans new PU safety shoe production lines and modular upgrades. The scope can combine metering equipment, molds, formulation support, commissioning, operator training and third-party testing support.
PU Safety Shoe Production Line and Upgrade Solution
Plan a new polyurethane safety shoe line or upgrade an existing one. Equipment, formulations, molds, controls and training are configured to the shoe design, target output and applicable finished-product tests.
Consistent and controllable performance across batches.
Precise measurement and closed-loop control systems ensure consistent material properties across batches of PU shoe soles.
Project delivery focused on compliance
Assist in third-party laboratory testing and facilitate market access for PPE-CE, LA, and REACH SVHC.
The equipment does not include an integrated system for online testing of finished product performance. All safety shoe protective measures must be verified by a reputable third-party laboratory, and the production line cannot replace the third-party testing required to assess the finished product's resistance to various conditions and chemicals.
From needs assessment to successful implementation of compliant mass production.
The standard project workflow for delivering polyurethane safety shoes includes: requirement definition, feasibility validation, factory-level testing, and on-site production delivery.
Pre-sale sample verification
Based on the target shoe type, desired level of protection, and operating conditions, a custom polyurethane (PU) formulation is developed. Small batches of samples are produced, and performance pre-testing is conducted by a third-party laboratory before a final price quote is provided.
On-site survey and process design.
Engineers conduct on-site assessments of the workshop environment, confirming production targets, certification requirements, and existing equipment capabilities. This allows for the development of customized layouts, formulations, and injection molding processes, with feasibility validation.
Equipment manufacturing and in-house calibration
Haifeng manufactures a new line or prepares modular upgrades, then checks metering, mixing, molds and control interfaces in-house before shipment.

Equipment for PU Safety Shoe Production
Explore Haifeng's safety shoe and PU sole foaming machines. The final equipment, molds and automation level depend on the target shoe.
Low-Pressure PU Foaming Machine | Safety Shoes
Low-pressure PU foaming machine designed for safety shoe sole casting, ensuring uniform density and oil-resistant, anti-slip performance. Ideal for protective footwear and industrial safety boot production.
Low-Pressure PU Foaming Machine | Shoe Soles
Low-pressure PU foaming machine for shoe sole production, designed for low-viscosity materials to produce lightweight, durable, and dimensionally stable soles. Ideal for sports and safety footwear.
Key advantages of the plan
This project focuses on optimizing the production process for polyurethane safety work boots, with an emphasis on achieving scalability, process flexibility, and adherence to project requirements.
High-precision measurement output
The accuracy of the measurement is ≤±0.3%, with stable proportions, reducing raw material waste, and uniform foam density in the shoe sole. These indicators only apply to raw materials and stable production conditions as specified in the agreement.
Complete module assembly
The project supports the construction of a new production line, or alternatively, the modular modification of existing, outdated lines, avoiding the need for a complete equipment replacement and thus controlling project costs.
Complete process technology delivery
The delivery scope can combine equipment, PU formulation support, mold adaptation, on-site commissioning and operator training.
Focusing on compliant production
The line can support low-VOC process planning and sample preparation for independent finished-shoe testing. Certification is determined by the relevant third-party assessment.
