Wall Panel Making Concrete Prefab Machine Lightweight Precast Concrete Hollow Core Slab Production Line

It produces lightweight precast wall panels and hollow core slabs (precast concrete boards) with a standard cross-section of 600 mm width and thickness options of 90 mm or 100 mm. The line forms hollow cores in the slab to reduce weight and improve thermal performance.

Two models are listed: 90*600 and 100*600. Both share the same power, voltage and external dimensions; the 90*600 produces L×600×90 mm panels with 7 holes Ø58 mm and a hollow rate of 34.6%, while the 100*600 produces L×600×100 mm panels with 7 holes Ø68 mm and a hollow rate of 32.6%.

Dimensions: 2500 × 900 × 750 mm. Weight: approximately 950 kg (90*600) or 1000 kg (100*600). Power: 5.5 kW; Voltage: 380 V, 50 Hz. A stable 3-phase power supply and adequate grounding are required.

Typical production efficiency is 1.5–3 m/min of finished panel/slab. Actual throughput depends on mix design, curing schedule, operator skill and line configuration.

Standard finished cross-sections are L × 600 × 90 mm (model 90*600) and L × 600 × 100 mm (model 100*600). Hollow rates are approximately 34.6% for the 90 mm panel and 32.6% for the 100 mm panel. Length (L) can be cut per project requirements.

Basic materials are cement, aggregates (sand, fine aggregates), water and any required admixtures (plasticizers, accelerators, etc.). Specific mix proportions should be designed for desired strength, weight and workability. Reinforcement or inserts can be added depending on structural needs.

The lightweight wallboard offers good thermal insulation: a 9 cm thick board is claimed to provide thermal performance equivalent to a 24 cm brick wall or a 20 cm aerated block wall. According to the description, panels can meet national standard thermal requirements without additional insulation in many cases.

The panels are made from inorganic materials and are non-combustible and do not produce toxic gases in fire. A 9 cm thick lightweight wallboard can achieve up to approximately 2 hours of fire resistance according to the product information.

Yes. The lightweight panels have a low elastic modulus and fast impact energy absorption, contributing to good seismic performance. The product description indicates the seismic level can reach level VII (seismic intensity VII), but final seismic design should follow local codes and engineering verification.

Yes. The wallboards can be sawed, cut and chiseled to create grooves for electrical and plumbing installations. This makes embedding line pipes and performing node treatments during construction convenient compared with traditional brick walls.

One advantage is reduced wet work: panels typically do not require traditional plastering, which minimizes on-site wet operations and construction waste. This helps keep the site cleaner and speeds overall construction progress.

Curing method depends on mix and production schedule. Natural (moist) curing or accelerated curing (steam or heat-assisted) can be used to achieve required strengths faster. Selection should follow the concrete mix design and production throughput targets.

You need a flat, level working area capable of supporting the machine weight, access to 380 V three‑phase power, water supply and drainage, and lifting equipment for handling panels. Ensure adequate working space for material staging and safe operator access.

Routine maintenance includes lubrication, inspection of mechanical parts, checking electrical connections and cleaning formwork and molds. Operator training is recommended for safe and efficient operation; many suppliers provide commissioning support and training. Confirm warranty terms and after-sales service details with the manufacturer or supplier.

Many manufacturers offer customization (panel thicknesses, hole layouts, automation level, length capability or auxiliary equipment) to meet project requirements. Discuss specific customization needs—panel dimensions, hollow core diameter, production capacity—with the supplier to confirm feasibility.
