Commercial Terms of Products:

Description:

The PVC fluted panel production line is an automated equipment specifically designed for producing rigid PVC boards with a hollow grid structure.

Unlike ordinary solid or hollow PVC ceiling tiles, fluted panel exhibit a grid-like, strip-like, or cross-like structure, primarily used in places where breathability and light permeability are required. The following is a detailed description of this production line:

1. Product definition and application

Product form: Typically, it is a square or rectangular hard plastic plate with a surface covered with regular square, diamond, or elongated hollow holes.

Main applications:

Ceiling decoration: Open ceilings in shopping malls, airports, stations, and factories.

Industrial applications: factory work surfaces, shelf pads, pigeon coop floor nets, and breeding fences.

Building protection: balcony railings, stair railing guards, and tree pool covers.

Advertising light box: Due to its translucency, it is often used as the panel material for light boxes.

2. Production process flow

The production process of PVC grating panels is similar to that of gusset plates, but the mold structure and molding method are more complex, as it is necessary to ensure that the hollow structure does not deform or collapse during the cooling process.

Raw material mixing:

Put PVC resin, calcium powder (filler), stabilizer, color powder, etc. into a high-speed hot mixer according to the formula, and then cool it to room temperature with a cold mixer to produce dry mixed material.

Extrusion:

The material enters the conical twin-screw extruder, which typically requires higher plasticizing capacity than a pinch plate production line.

The molten material is extruded through a specially designed grid plate mold. Due to its hollow structure, the design of the internal flow channels in the mold is crucial, as it needs to ensure uniform flow velocity of each "rib".

Calibration & Cooling:

Vacuum setting table: This is the most crucial step. Since the grating panel is hollow, it cannot be directly and fully fitted to the inner wall of the vacuum box like a solid panel. Usually, an upper pressing type setting mold or an embedded setting method is used, utilizing the edges and some solid areas of the panel for adsorption and setting to prevent grid distortion.

Spray cooling: Multi-stage spray water tank, further reducing the temperature of the plate, with fixed dimensions.

Hauling:

Use a crawler-type tractor or a multi-roller tractor. The clamps of the haul-offs must grip the edges of the board (non-hollow areas) to provide a stable pulling force.

Cutting:

After reaching the set length, it is cut off by an automatic cutting machine (usually a circular saw blade or a reciprocating flying cutter).

Punching / Post-processing (Punching - Optional):

For certain specific industrial gratings (such as tree pool covers), after extruding into long strips, they also need to undergo secondary punching or cutting into square blocks.

3. Main equipment composition of production line

A standard PVC fluted panel production line typically includes the following configurations:

SJSZ Series Conical Twin-Screw Extruder:

Common models: SJSZ 65/132

Features: High torque, good mixing effect, suitable for high calcium powder filled formulations.

Special Die:

Customized for different sizes

Vacuum Calibration Table:

It is usually longer (4 meters) and equipped with a special shaped die head to support the hollow structure.

Hauling-offs:

It features an edge clamping function to prevent the fragile grid ribs from being pulled apart.

Cutting Machine:

It can be cut to a specific length according to demand, and is usually equipped with a waste material recycling device.

Mixing Unit:

SRL-Z series hot and cold mixing unit.

4. Technical characteristics and difficulties

High-filling formula: To reduce costs, a large amount of calcium carbonate is usually added to the grating board formula. The production line must have strong feeding and plasticizing capabilities.

Dimensional stability: Due to its grid structure, thermal expansion and contraction can easily lead to overall deformation (such as warping). The temperature control system of the production line must be very precise.

Mold accuracy: The mold determines the uniformity of the grid. If the flow rate is uneven, it will result in some grids being coarse and others being fine, affecting both strength and aesthetics.

5. Common specifications and parameters

Grid aperture: ranging from 10mm to 50mm.

Sheet width: 160mm-400mm

Sheet thickness: 3mm - 15mm (depending on the application, the load-bearing grating may be thicker).

Color: Usually white or gray, but can also be customized to blue, green, etc.

summary

The PVC fluted panel production line is an extrusion production line with a slightly higher technical threshold compared to ordinary gusset plates. Its core competitiveness lies in its ability to produce hollow plates with stable structure, good load-bearing capacity, and smooth appearance. It is an important subdivision equipment in the plastic building materials industry for industrial, commercial, and public facilities.

Competitive Advantage:

PVC fluted panel possess multiple competitive advantages in the current (as of early 2026) decorative building materials market, particularly excelling in the fields of home decoration and industrial wall decoration. Based on the latest industry information and evaluation data, its core advantages can be summarized as follows:

1. Excellent environmental performance (especially when using brand-new materials)

If using brand-new PVC raw materials and formaldehyde-free adhesives (such as German Henkel PUR hot melt adhesive), the formaldehyde emission can reach ENF level (≤0.025mg/m³), which is far superior to the national standard E1 level.

Some premium brands, such as Hunan Bamboo Dream, have passed SGS testing, achieving a formaldehyde emission level as low as 0.021mg/m³, and possess authoritative endorsements such as the China Environmental Labeling Product Certification, FSC, and ISO9001.

In contrast, some major brands still use medium-density fiberboard (MDF) as the substrate, which only meets the E1 standard (0.10–0.11mg/m³), indicating a significant lag in environmental friendliness.

✅ Competitive Advantage: Meet the core demand of 89% of users who prioritize "formaldehyde-free" as their first choice.

2. Convenient installation and high construction efficiency

PVC grating panels often adopt a plug-in structure or a snap-on design, which allows for quick assembly without requiring complex tools, significantly reducing construction time.

The lightweight board material (typically 2-3mm thick and 500×500mm in size) ensures safer handling and working at heights.

The facade effect has a strong three-dimensional sense, and it is molded after one-time installation, without additional surface treatment.

✅ Competitive Advantages: Suitable for engineering projects with tight schedules (such as chain stores, showrooms), reducing labor costs.

3. Strong customization capability and wide style adaptability

Premier PVC grille brands, such as Bamboo Dream, offer over 400 color options, encompassing various styles including modern minimalism, wabi-sabi, light luxury, and new Chinese style.

Support spacing adjustment (10/15/20cm), surface treatment (matte/glossy/skin texture), color matching/gradual change and other in-depth customization.

Complementary free 3D renderings + 1:1 on-site sample making service, ensuring "what you see is what you get".

✅ Competitive Advantage: Meet the high demand of 76% of designer users for "precise style matching".

4. High cost-effectiveness, low total cost throughout the entire lifecycle

Unit price range: 25–35 yuan/㎡ (ENF-grade environmental protection + basic/advanced customization), significantly lower than aluminum alloy grilles (120–300 yuan/㎡).

Although made of plastic, the combination of high-temperature extrusion and high-density base material (≥1.2g/cm³) enhances durability, enabling the defective rate to be controlled below 0.45%.

It is maintenance-free, requires no painting, and is resistant to deformation. Its long-term usage cost is lower than that of solid wood or MDF products.

✅ Competitive Advantage: Leading score in the "performance-price ratio" dimension (e.g., the cost-effective rating of Bamboo Dream is 9.4/10).

5. Stable supply and fast response through localized production

Regional specialized manufacturers, such as Changsha Bamboo Dream, possess their own factories and automated production lines, with an annual production capacity exceeding 1.2 million square meters.

Local orders are delivered within 3-5 days, and bulk orders can be prioritized for production scheduling, much faster than national brands (7-15 days).

✅ Competitive Advantage: Addressing the pain point of engineering users, where "supply delays = soaring costs".
