1. Executive Summary

Hebei Xinnuo Roll Forming Machinery Co., Ltd. (hereinafter “Xinnuo” or “Huayu Machinery”) today announced that its turnkey EPS sandwich panel production line and full auxiliary equipment package continue to gain strong traction across the Brazilian market. Centered on the EPS sandwich panel main forming line, the solution integrates corrugated tile machines, arch curving machines, ridge cap roll formers, C/Z purlin machines, and other complementary cold roll forming equipment — enabling Brazilian building material manufacturers to source everything from roof panels and wall panels to structural purlins under a single supplier, completing entire factory builds within one procurement ecosystem.

With nearly three decades of manufacturing heritage tracing back to the original Huayu Roll Forming Machine Factory (established 1998), dual ISO/CE certification, a self-developed PLC control platform, and a 0.05mm precision glue-roller base, Xinnuo has earned its position as one of the most trusted Chinese machinery suppliers to Brazil’s light steel construction sector, with equipment operating in over 80 countries worldwide.

2. Company Credentials — Who Is Building Your Equipment?

Hebei Xinnuo Roll Forming Machinery Co., Ltd. is headquartered in Botou City, Hebei Province — the heartland of China’s cold roll forming machinery industry. Its manufacturing legacy began in 1998 with the founding of the Huayu Roll Forming Machine Factory (华宇压瓦机厂), the direct predecessor to today’s operation.

Industry Insight: A composite panel production line represents a baseline investment of approximately RMB 1.5 million (≈ USD 210,000). Choosing an experienced manufacturer with proven manufacturing depth is critical — a single batch of defective panels from an unreliable machine can cost RMB 10,000–20,000 in wasted material, and more critically, can cost you market trust and customer relationships that took years to build.

3. Core Product: EPS Sandwich Panel Production Line in Detail

3.1 What Is an EPS Sandwich Panel?

An EPS sandwich panel is a lightweight, thermally insulated structural building panel composed of three layers:

Top Steel Skin     — Color-coated galvanized steel, 0.3–0.8mm thickness
─────────────────────────────────────────────────────────
EPS Insulation Core — Expanded polystyrene foam: lightweight, thermally efficient, cost-effective
─────────────────────────────────────────────────────────
Bottom Steel Skin  — Color-coated galvanized steel, 0.3–0.6mm thickness

The three layers are permanently laminated under heat and pressure using industrial-grade adhesive. The resulting panel combines structural rigidity with outstanding thermal insulation performance, making it the preferred cladding material for industrial factories, cold storage facilities, logistics warehouses, livestock farms, and prefabricated buildings across Brazil.

3.2 How the Machine Works — Production Process

The EPS sandwich panel production line operates through the following sequence:

Dual Decoiling

1. → Two independent decoilers simultaneously feed the top and bottom steel coils

Upper & Lower Roll Forming

2. → The upper forming unit and lower forming unit synchronously roll-form the steel sheets into the desired profiles (e.g., 970-type, 1050-type, 950 concealed-cap)

Adhesive Injection & Lamination

3. → A four-pump dual-circuit adhesive system evenly applies two-component (A/B) glue; 54 large-diameter (Φ180mm) rubber-covered laminating rollers press the top skin, EPS core, and bottom skin into a unified panel

Curing & Stabilization

4. → The composite panel passes through a pressing and curing zone for full adhesive setting

Precision Cut-to-Length

5. → The dual-cutting system (separate blades for EPS vs. rock wool) slices panels to exact specified lengths

Automatic Stacking

6. → Finished panels are automatically collected and stacked at the output end

3.3 Core Technical Specifications

3.4 Core Technical Advantages — Why Choose Xinnuo

① 0.05mm Precision Laminating Base — Where a Flat Panel Begins

The glue-roller mounting base is machined in a single pass on a 12-meter Taiwan CNC gantry mill, holding flatness within 0.05mm — four times tighter than the industry norm of ±0.2mm. This precision directly governs absolute roller parallelism. If the rollers are not perfectly level, the panel comes out with surface ripples. Xinnuo’s 0.05mm base is the foundational guarantee of panel surface flatness at production speed.

② 54 × Φ180mm Grade-A Laminating Rollers — The Physics of Bond Strength

Upgraded to 54 large-diameter rubber-covered rollers (industry average: 32–40 rollers). Greater total contact area means longer dwell time under pressure, producing measurably stronger adhesive bonds between the EPS core and steel skins. The Grade-A environmentally certified rubber compound meets EU VOC standards and runs smoother with less vibration — especially critical when producing glass wool panels and cleanroom panels where surface quality is non-negotiable.

③ Patented One-Way Steel Belt Conveyor — Industrial Design That Never Jams

Xinnuo’s patented one-way steel belt system employs a bicycle freewheel principle: active material feed, passive belt advance. This design eliminates steel belt jamming entirely — a chronic headache on conventional bidirectional belt systems. With four-axis adjustable (up/down/left/right) positioning heads, panel width changes require no mechanical reconfiguration. This mechanism has been proven through nearly three decades of continuous production refinement and is the signature differentiator between a Xinnuo composite panel line and generic alternatives.

④ Four-Pump Dual-Circuit Adhesive Delivery — Precise Ratio, Predictable Cost

Four independently controlled adhesive pumps with dual motors and dual VFDs deliver A-component and B-component adhesive through separate circuits. The mixing ratio is digitally adjustable with precision that single-pump blended systems cannot match. Real-world results: approximately 20% adhesive savings, more consistent bond strength, and elimination of the common failure mode where pre-mixed adhesive cures inside the plumbing and blocks the lines.

⑤ In-House Programmed PLC — One Video Call Away from a Fix

The entire electrical control system is programmed by Xinnuo’s own engineering team using Delta PLC and Delta VFD hardware. No third-party outsourcing. When an electrical issue arises, the customer does not wait for an external engineer to travel — one video call (WeChat or WhatsApp) is sufficient for remote diagnosis and repair. For overseas markets like Brazil with a 12-hour time difference, this translates to avoiding days of costly production downtime.

⑥ 5.6 Metric Tons Total Weight — Material Honesty

A Xinnuo composite panel machine weighs 5.6 metric tons — approximately 40% heavier than comparable machines from smaller workshops. The main frame uses 200×100mm rectangular steel tube (upgraded from 180×80mm), the main drive motor is rated 5.5 kW, and the conveyor extends to 5.9 meters. Between “4 tons” and “5.6 tons” lies the difference in structural rigidity, long-term precision retention, and total service life. Steel does not lie.

⑦ Dual-Cutting System — Separate Blades for EPS and Rock Wool

The cutting section features two independent blade sets optimized for EPS foam and rock wool respectively. Separate cutting extends blade life, reduces replacement cost, and produces cleaner cut edges on both material types. The cutting enclosure is equipped with a dust extraction and collection system for environmental compliance.

⑧ 12-Station Self-Locking Edge Forming — Cleaner, Straighter Folds

The self-locking panel edge-forming section is upgraded from the industry-typical 9 stations to 12 stations, with a 50mm main shaft diameter (competitors: 40mm). Each station incorporates additional bearings for greater stability. The result: consistently straight, parallel edge folds that lock securely and present a professional finished appearance.

4. Complete Auxiliary Facilities — One Supplier, One Standard, One Support Team

7. Frequently Asked Questions

Q1: Is the EPS panel machine the same equipment as a rock wool panel machine?

Yes. Xinnuo composite panel machines are designed as EPS/rock wool integrated units. When switching core materials, the EPS mode uses the adhesive pump system for lamination; the rock wool mode feeds rock wool blankets automatically via the mineral wool feeder — no adhesive required. The cutting system also features dual-cutting (separate blades for EPS and rock wool). A single machine produces both panel types, reducing total equipment investment.

Q2: Will the equipment work on Brazil’s 60 Hz power grid?

Yes. All Xinnuo machines exported to Brazil are equipped with 220V/380V 60 Hz motors and VFDs as standard. Every machine is tested and commissioned under 60 Hz operating conditions before leaving the factory. Transformers and control cabinets are configured to Brazilian standards.

Q3: How much factory floor space do I need?

A standard single-layer EPS sandwich panel production line requires approximately 50m × 12m × 5m (L × W × H) of factory space. If auxiliary tile machines, purlin machines, etc. are included, budget approximately 800–1,000 square meters total. Xinnuo provides complete foundation drawings and factory layout plans so customers can verify precise equipment placement dimensions before breaking ground.

Q4: How often do the laminating rollers need replacement?

Grade-A rubber-covered laminating rollers, under normal maintenance, have a service life of 3–5 years (based on 8-hour daily production). We recommend customers order 1–2 spare rollers with the initial purchase to avoid a full line stoppage if a single roller degrades.

Q5: What is the real difference between your equipment and other Chinese suppliers?

The core differences come down to four points: ① 12-meter gantry-milled 0.05mm precision base (smaller workshops use segmented welding with poor flatness); ② 54 × Φ180mm large laminating rollers with four-pump separated adhesive delivery (smaller workshops typically use 32–40 smaller rollers with a single pump); ③ patented one-way steel belt conveyor (smaller workshops use ordinary conveyor belts prone to jamming); ④ in-house programmed PLC (smaller workshops outsource programming and depend on third parties when faults occur). Beyond these four, the numbers speak for themselves: 5.6 tons total weight and 150 units annual output are figures only possible with genuine manufacturing depth.

Q6: How long does installation take? How are the Chinese engineer’s travel costs to Brazil handled?

Standard installation and commissioning takes 15–20 working days. The Chinese engineer’s travel costs to Brazil (international airfare + accommodation + visa) are typically covered by the customer, with the exact amount specified in the contract. A lower-cost remote video-guided installation option is also available.

Q7: What is the warranty policy?

Full machine warranty: 12 months from the date the equipment arrives at the Brazilian port. During the warranty period, parts that fail due to non-human factors are replaced free of charge (international shipping costs borne by the customer). Lifetime paid maintenance and spare parts supply are provided. The following are excluded from warranty coverage: improper operation, unauthorized modifications, natural disasters, and adhesive pump blockages caused by using non-specified adhesive products.
