The vertical foam production process for PU soft foam, developed in the 1980s, features space efficiency, reduced waste, and versatility in block shapes. This article discusses challenges and solutions for optimal production.
This abstract discusses common issues in polyurethane soft foam production, such as bubble formation, foam collapse, and surface cracking. Solutions include adjustments to catalyst ratios, silicone oil quantities, and process parameters to ensure optimal foam quality.
This article discusses defects in the production of high rebound polyurethane foam, including shrinkage, internal hollowing, residual odors, and surface pores. Solutions are proposed, addressing issues related to tooling molds, raw materials, gelation, foaming reactions, and stabilizer dosage, contributing to improved foam quality.
The main factors affecting the resilience of polyurethane foam are: 1. Cell Opening Rate; 2.Cell Shape; 3.Cell Pore Size and Distribution; 4.Polyether Polyol; 5.Isocyanate; 6.Other Factors
Design Standards for Foam Molds:1.Materials; 2.Foam Leakage; 3.Joints; 4.Maintenance; 5.Mold Action Sequence; 6.Pneumatic Components; 7.Pressure Plates
While foam machinery may appear to have a simple operating principle, its internal structure is complex, making maintenance a highly technical task.
Foam cutting machines are efficient tools for cutting and processing various foam materials, providing convenience for production and manufacturing.
The use and maintenance of the rebonded foam machine(rebonding foam machine) should pay attention to several aspects:
The key factors in the polyurethane foaming machine foaming process are: 1. Temperature Control, 2. Pressure Control, 3. Component Metering, etc.
High resilience foam is renowned for its impressive mechanical properties, a relatively high compression load ratio for enhanced seating comfort, exceptional fatigue resistance, and notable breathability and flame resistanc
