What Pioneer Delivered

Not just a machine — a matched system, a trained crew on site, and after-sales backing end to end.

• An on-site review of the panel line and 2,500m² roof schedule, sizing the cavity gap and daily output so the textile hall finished on time.
• A single-source system — the JYYJ-Q300 machine and matched Pioneer foam tuned and warranted together, not a budget machine and mystery chemicals from three suppliers blaming each other.
• A spray crew trained to hold 12 kg/m³ core density to ±1 kg/m³ across a high-output pneumatic run — the hard part of panel foam is the operator, and we own it.
• QA on cavity fill and a spray schedule built around the factory expansion window — 2,500m² of insulated roofing completed in 6 days, not weeks.
• Ongoing remote support for output and ratio tuning, plus easy re-order of the exact matched All-Water foam — so the next panel run is a phone call, not a new sourcing project.

Execution Process

1. 1 · Panel Cavity Prep

   Steel panel skins are degreased and dried, then the cavity gap is set with spacers for a uniform 50mm core thickness. Skin temperature is checked so the open-cell foam rises and bonds evenly between the sheets.

2. 2 · Pneumatic Machine Setup

   The JYYJ-Q300 pneumatic unit is primed with Pioneer All-Water A-component and matched B-component, output set within the 2-12 kg/min band at 25 MPa. A short test shot confirms density before production spraying begins.

3. 3 · Open-Cell Core Spray

   50mm open-cell PU foam at 12 kg/m³ is sprayed between the steel skins, the stable pneumatic output holding density to ±1 kg/m³ across the 2,500m² roof. A 2-person crew sustains roughly 420 m² of finished panel per day.

4. 4 · Trim, Cure & Closure

   Excess rise at panel edges is trimmed flush, then the core cures and the panels are closed and fixed to the roof structure. Each completed panel is checked for full cavity fill before installation on the production hall.
