Low pressure pu machine
Yongjia low pressure polyurethane foaming machines are widely used in the production of PU Stress Balls. The machines employ a PLC intelligent control system, allowing for precise adjustment of the filling volume to adapt to different size and density requirements. Combined with Yung-Chia’s specialized foaming formulas and mold solutions, customers can achieve efficient mass production, reducing defect rates and material waste.
Mixing Head
The low-pressure mixing head provides gentle yet thorough PU mixing, ensuring soft, elastic foam ideal for stress balls. Its leak-free design and precise ratio control guarantee smooth surfaces and consistent rebound quality.
Siemens PLC System
The Siemens PLC provides smart automation for stress ball production. It coordinates the mixing and dispensing process precisely, ensures consistent foam quality, and simplifies monitoring and control for smooth operation.
Metering Pump System
The metering pump delivers PU components accurately and steadily for stress ball production. It ensures uniform foam density, consistent elasticity, and minimizes material waste for efficient production.

SPU-LS2 Model Range for Reference
The parameters above are typical for stress ball production (small shot size). For the full SPU-LS2 low-pressure model range (roughly 15-2,500 g per shot), see the specification table on the Low-Pressure PU Foam Machine page and confirm the exact model with our engineers once ball size and daily target are set.
Configuration Decisions
| Decision | Why it changes the equipment scope |
|---|---|
| Ball diameter and shot size | Sets the required flow range and which SPU-LS2 model fits — small parts typically use the SPU-LS2-60 range. |
| Target density | Typically 18-25 kg/m³; affects ratio control and cure time. |
| Mold count | Number of cavities run per cycle determines whether one dispensing position is sufficient. |
| Color/formulation changes | Frequent color changes call for more PLC recipe slots and faster cleaning/purge capability. |
What Changes the Quotation
Price and lead time depend on the shot size, mold count, colorant/formulation-change frequency and daily production target. A useful quotation starts with the ball specification and target output, not only the words “low-pressure machine.”
FAQs
Does this machine include the stress ball molds?
Not automatically. The foaming machine meters and mixes the material; molds are quoted separately based on ball diameter and quantity per cycle.
Can it handle multiple ball sizes or colors?
Yes, within the flow range of the selected model — PLC recipe storage supports switching between sizes, densities and colors, though changeover time should be confirmed against the actual product mix.
What is the typical shot size for a stress ball?
Small stress balls typically fall in the SPU-LS2-60 model range; the exact shot size depends on ball diameter and target density.
What should be sent for a useful quotation?
Ball diameter(s) and target density, daily production target, mold quantity, and colorant or formulation requirements.
