PVC Flooring Production Line Capacity: Converting kg/h to Saleable m²/Day

A PVC flooring production line rated at 1,000 kg/h does not automatically produce a fixed number of square meters per day. Daily saleable output depends on the flooring construction, material weight per square meter, operating hours, production losses and the capacity of downstream equipment.

For a flooring manufacturer, the practical question is: How many square meters of accepted finished flooring can the complete line produce within the available production schedule?

This guide explains how to convert kg/h into saleable m²/day, compare capacity claims and work backward from a daily production target.

All numerical examples below are hypothetical planning calculations, not Kingshine equipment specifications or guaranteed output.

The Basic Conversion Formula

When kg/h represents actual gross core output during running time, use:

Saleable m²/day = core output in kg/h × running hours/day ÷ core weight in kg/m² × area recovery × quality yield

If you start with planned production hours:

Running hours/day = planned production hours/day × availability

The combined calculation becomes:

Saleable m²/day = Q × H × A ÷ W × R × Y

For this formula, Q is measured at the gross formed-core output point. Any losses before that point are outside this particular conversion. Losses after it must be captured once in R or Y.

If quoted kg/h is an ideal or maximum rate, an additional performance factor may be needed to represent the expected average running rate. Do not add that factor when Q already reflects actual operating speed.

The calculation estimates what the forming section can supply. The complete factory must also have enough finishing capacity to convert that supply into saleable flooring.

First Confirm What the kg/h Rating Includes

Before calculating square meters, ask what material the quoted hourly output represents.

A core extruder's output may exclude decorative film, wear layer, coating and attached underlay. Dividing core-only kg/h by the total finished plank weight mixes two different material boundaries.

For example, suppose:

• Core output is 1,000 kg/h.

• Core weight is 8.0 kg/m².

• Total finished flooring weight is 8.5 kg/m².

Gross core area output is:

1,000 ÷ 8.0 = 125 m²/h

Dividing by 8.5 would produce approximately 117.6 m²/h, but that calculation incorrectly assigns the weight of separately added layers to the core extruder.

Those additional layers still need sufficient feeding, lamination and finishing capacity. They simply belong to a different part of the material balance.

Calculate Flooring Weight per Square Meter

For a uniform solid layer:

Weight per m² = thickness in meters × density in kg/m³

When thickness is entered in millimeters:

Weight per m² = thickness in mm × density in kg/m³ ÷ 1,000

A hypothetical 4 mm core with a density of 2,000 kg/m³ has a weight of:

4 × 2,000 ÷ 1,000 = 8.0 kg/m²

Use the density of the formed material. Loose powder bulk density is not the correct value for this calculation.

For a multilayer product, calculate each relevant layer separately or weigh representative samples with a known area. Match the included layers to the kg/h measurement point.

If the flooring includes a foam backing, do not multiply total finished thickness by the rigid core density. Different layers can have very different densities.

For irregular sections, profiled edges or complex constructions, measured mass and agreed coverage area may provide a better basis than a simple thickness calculation.

Worked Example: From 1,000 kg/h to Daily Saleable Area

Assume the following operating conditions:

Step 1: Calculate core weight

4.0 × 2,000 ÷ 1,000 = 8.0 kg/m²

Step 2: Calculate running time

20 × 0.85 = 17 hours/day

Step 3: Calculate gross core area

1,000 × 17 ÷ 8.0 = 2,125 m²/day

Step 4: Apply area recovery

2,125 × 0.95 = 2,018.75 m²/day

Step 5: Apply quality yield

2,018.75 × 0.98 = approximately 1,978 m²/day

Under these assumptions, the forming section supports approximately 1,978 saleable m²/day, provided downstream equipment can process the corresponding volume.

The result excludes any additional constraint from finishing, packaging or inventory release. It also assumes the stated output and yields remain representative throughout the production period.

Comparing 500, 1,000 and 2,000 kg/h

The following table uses the same hypothetical assumptions: 8.0 kg/m² core weight, 20 planned hours, 85% availability, 95% area recovery and 98% quality yield.

This is a mathematical comparison, not a product selection table.

Doubling extrusion output doubles calculated area only when the other assumptions remain unchanged. In a real factory, material preparation, cooling, finishing, staffing or packaging may prevent that increase from reaching the saleable output stage.

How Thickness Changes m²/Day

At the same mass output and density, a thicker core requires more kilograms per square meter.

Using 1,000 kg/h, a density of 2,000 kg/m³ and the operating factors from the previous example:

These figures hold kg/h constant to demonstrate the conversion. They do not establish that one machine can maintain identical mass output across every thickness.

Thinner products may require higher line speed to sustain the same kg/h. Thicker products may introduce different cooling or handling requirements. Confirm the achievable output for each intended specification.

Density also changes the conversion. A higher-density core contains more kilograms per square meter at the same thickness. Changing the formulation solely to improve the numerical area calculation is not a substitute for meeting product performance requirements.

Separate Downtime, Speed Loss and Material Loss

A reliable capacity model accounts for each loss once.

Availability describes how much planned production time is actually spent running.

Performance describes the running rate relative to a defined ideal rate.

Quality yield describes the proportion of output that passes the agreed acceptance criteria.

These are the three factors used in overall equipment effectiveness, or OEE. For flooring planning, cutting and profiling area recovery may also need separate treatment because planned geometric material removal is not automatically a rejected finished piece.

Use one consistent method:

• If Q is the ideal rate, apply a justified performance factor.

• If Q is the actual average running rate, speed losses are already included.

• If hours are actual running hours, do not multiply by availability again.

• If output already means accepted finished area, do not deduct the same quality losses again.

For example, if an ideal rate is 1,000 kg/h and expected running performance is 90%, use 900 kg/h in the worked example. Estimated saleable output becomes approximately 1,781 m²/day.

Do not assume that a generic “efficiency” percentage covers downtime, trim, rejection and reduced speed in a known way. Request a definition.

Account for Cutting, Profiling and Recycled Scrap

Area recovery connects gross sheet production with finished flooring coverage.

It may reflect edge trim, cutting layout, saw kerf, end trimming and the coverage dimensions associated with the finished joint design.

For click-lock flooring, use the agreed net coverage dimensions. The maximum physical width across a projecting joint may not equal the installed coverage width.

Keep area recovery separate from mass recovery. Milling away part of an edge profile changes mass, but the relationship between removed mass and lost coverage area is not necessarily one-to-one.

If a combined recovery factor already includes cutting losses and final rejection, use that combined factor once. Do not multiply by additional factors covering the same losses.

Recycling scrap can reduce material purchases, but it does not instantly restore production capacity. Reprocessed material uses equipment time, and repeated passes must not be counted as additional saleable output.

Check the Downstream Bottleneck

A PVC flooring production line is a sequence of operations. Its sustainable finished output is limited by the stage with the lowest effective capacity after all stages are expressed on the same basis.

Review:

• Mixing and material supply.

• Forming and lamination.

• Cooling, conditioning or thermal treatment where required.

• Surface coating and curing.

• Cutting and click profiling.

• Backing application.

• Inspection, packing and material handling.

Suppose the forming section can support 1,978 saleable m²/day, but finishing can deliver only 1,700 accepted m²/day under the same working schedule.

Sustainable finished production is approximately 1,700 m²/day unless the constraint is resolved. Extra sheet production becomes intermediate inventory.

Compare every stage in equivalent final accepted m²/day. Do not compare gross sheet capacity with already accepted packing output without adjusting for the remaining losses.

Buffers can help separate short interruptions between stages, but they do not remove a persistent capacity shortage. Similarly, conditioning time affects space, work in progress and lead time; it does not necessarily reduce steady daily throughput if sufficient capacity and storage are available.

Cross-Check Using Line Speed or Piece Count

Mass-based calculations should agree reasonably with physical production measurements.

For gross sheet output:

Gross m²/h = sheet width in meters × actual line speed in m/min × 60

For example:

1.2 × 1.74 × 60 = 125.28 m²/h

At 8.0 kg/m², that corresponds to approximately 1,002 kg/h. Small differences may result from rounding or measured thickness and density variation.

Use the same sheet width and material boundary as the mass calculation. If width is already trimmed, do not deduct that trim again.

For accepted finished planks:

Saleable m²/h = accepted pieces/min × coverage length in meters × coverage width in meters × 60

If 10 accepted planks per minute each cover 1.22 × 0.18 m:

10 × 1.22 × 0.18 × 60 = 131.76 m²/h

This separate example illustrates the counting method. Apply running hours only if the count is measured per running minute; if the average already includes downtime, use the corresponding elapsed period.

Work Backward from a Daily Production Target

To size the forming section:

Required actual running kg/h = target saleable m²/day × core kg/m² ÷ (planned hours × availability × area recovery × quality yield)

For a target of 3,000 saleable m²/day using an 8.0 kg/m² core and the previous operating assumptions:

Required kg/h = 3,000 × 8.0 ÷ (20 × 0.85 × 0.95 × 0.98)

Required actual running output = approximately 1,516 kg/h

If the starting point is an ideal capacity and expected running performance is 90%:

Required ideal capacity = 1,516 ÷ 0.90 = approximately 1,685 kg/h

These are planning requirements, not recommendations for a particular machine model. Verify the required rate with the intended formulation, thickness, width and finishing specification.

For mixed production, calculate required hours for each product separately and add changeover time. An unweighted average thickness can misrepresent a schedule containing both thin and thick flooring.

What to Request in a Capacity Quotation

A useful quotation connects the machine's hourly output to your finished product target.

Ask for a product-specific trial that is long enough to demonstrate stable production and relevant downstream operation.

A short peak kg/h reading does not establish a complete day's saleable output. Capacity acceptance should specify both quantity and quality.

Frequently Asked Questions

1. How do I convert kg/h into m²/h?

Divide mass output by the matching product or layer weight per square meter. For example, 1,000 kg/h divided by 8 kg/m² equals 125 gross m²/h.

2. How many m²/day can a 1,000 kg/h line produce?

There is no fixed answer. In this article's hypothetical 4 mm core example, the result is approximately 1,978 saleable m²/day after the stated time and yield allowances.

3. Should I use core thickness or finished flooring thickness?

Use the thickness and mass corresponding to the quoted kg/h. Core-only output requires core weight; finished flooring output requires finished flooring weight.

4. Can I multiply hourly output by 24?

Only if the schedule and calculation genuinely represent 24 hours. Account for stops and other losses according to whether the hourly figure already includes them.

5. Is OEE the same as saleable area recovery?

No. OEE combines availability, performance and quality. Geometric cutting and profiling losses may require a separate area-recovery calculation.

6. Does click-lock flooring always have lower capacity than dryback flooring?

No. The result depends on product construction, dimensions, equipment and operating conditions. Click profiling adds a capacity requirement that must be checked.

7. Does recycling scrap increase saleable output automatically?

No. Reprocessing consumes capacity. Count accepted finished flooring once, regardless of how many times its material passes through the line.

8. Can the same machine maintain identical kg/h at every thickness?

Do not assume so. Verify the actual rate across the required thickness range and check cooling, line speed and downstream limits.

9. Is produced m²/day the same as shipped m²/day?

No. Conditioning, inspection, inventory and order release can separate production from shipment. Define the output point used in the capacity commitment.

10. What is the best capacity figure for factory planning?

Use sustainable accepted finished m²/day for a defined product mix and operating schedule, supported by stage-level capacity and trial data.
