What Materials Are Used in SPC Flooring Production?
Before we go through the process of how SPC Flooring is made it is best to understand all the layers of the flooring and the individual design of each of the layers in order to highlight the features and benefits of each layer to provide strength, stability and looks to the Flooring.
Core Components of SPC Flooring
Our SPC (Stone Plastic Composite) flooring is an Engineered Hardwood Flooring. SPC flooring is manufactured with a mix of natural stones and high-quality synthetic with just the right amount of each to provide a rigid core and high flexibility.
- Calcium Carbonate (Limestone Powder): This mineral acts as the structural foundation of SPC flooring, providing rigidity and dimensional stability that ensures minimal expansion or contraction under temperature fluctuations.
- Polyvinyl Chloride (PVC) Resin: Serving as the binding polymer, PVC resin enhances flexibility while maintaining the core’s toughness.
- Plasticizers and Stabilizers: These compounds improve elasticity, thermal stability, and processability during manufacturing.
- Decorative Film Layer: A printed film replicates authentic wood grains or stone textures using high-definition printing technology.
- Wear Layer: The top transparent coating protects against scratches, stains, and abrasion—essential for long-term durability in both residential and commercial spaces.
The Role of Additives in Material Performance
Additives play a major role in optimizing material performance.
- UV inhibitors prevent discoloration caused by prolonged sunlight exposure.
- Anti-bacterial agents enhance hygiene in high-traffic environments such as hospitals or offices.
- Impact modifiers strengthen resistance against heavy loads and foot traffic.
How Is the Core Layer Formed During Extrusion?
After raw materials have been prepared, they are extruded in a process that is crucial for core board’s density, evenness and mechanical properties of SPC.
Mixing and Compounding Process
Limestone powder is mixed with PVC-resin. Stabilizers and additives are weighed out precisely and mixed with the limestone powder on high-speed mixers. After the mix has cooled off it is introduced into the extruder where all the components are dispersed consistently.
Extrusion and Sheet Formation
The compound is then processed in an extruder, where temperature and pressure are kept under control in order to melt the compound. After melting, the compound is then extruded through a T-die die which is cut off to form extremely long and very thin sheets of constant thickness. These long thin sheets are then cooled by calendring rolls in order to produce two smooth surfaces and to fix the dimensions of the sheet for subsequent lamination operations.
How Is the Decorative Layer Applied?
These Core Sheets are produced as described above and then covered with a wide variety of surface films, which can resemble the look and feel of a variety of natural materials including real oak and even marble stone. The finished surface has been cleverly engineered using modern engineering techniques.
Lamination Process
Our decorative films are heat-laminated by hot pressing onto SPC core. Our films guarantee visual realism and mechanical robustness. They are glued perfectly, without any air bubbles, and do not come off.
Wear Layer Application
The transparent wear layer on top of the design film is usually between 0.3 mm and 0.7 mm thick in order to absorb scuffs and dirt in order to prevent stains while maintaining the design impression.
What Happens During Cutting and Profiling?
Large SPC panels after lamination are cut into planks or tiles in line with market requirements with the aid of accurate machinery.
Precision Cutting Techniques
Our computer-controlled saws are precision cut to exact size with minimal waste of trim. Our edge finishing also helps to produce straight and accurate wood installation.
Click-Lock Profiling Process
Special machines are used to mill the edges of Flooring. These machines create the connecting system between the Flooring planks such as Unilin or Valinge click-lock system. No nails, no glue – installation with tools only.
How Are Surface Finishing and Quality Inspections Conducted?
Hardwood floor planks are inspected multiple times before they are packed to check that they meet the necessary international performance criteria.
Surface Treatment Options
Les fabricants utilisent plusieurs techniques pour améliorer la surface :
- Embossing in Register (EIR): Aligns texture with printed patterns for lifelike tactile realism.
- Matte or Gloss Coatings: Adjust surface sheen according to design preferences or market trends.
- UV Coating: Provides additional stain resistance while preserving color vibrancy over time.
Quality Control Procedures
At Lanhe Flooring, Quality Control is of utmost importance to us. We have implemented strict production procedures within our factory to guarantee that our products will last. All of the flooring items that we manufacture are inspected for any surface defects before being case made and before they are shipped off to other countries around the world.

What Are Common Challenges Faced During SPC Flooring Manufacturing?
As production goes on at even the most advanced factory with modern technology, such as Lanhe’s fully automated plant, there will always be some problems to solve.
Material Homogeneity Issues
Differing levels of impurities in raw materials can create problems in terms of achieving consistent extrusion. By using strict sourcing and a batch testing regime to check for uniformity we are able to combat these effects.
Temperature Control During Extrusion
Local variations in heating profiles that create stresses within layers can be monitored and controlled using modern monitoring systems in order to guarantee a suitable temperature for melting the compounds.
Adhesion Between Layers
Failure of delamination can be caused by incorrect lamination temperature or by not applying sufficient pressure during lamination. Continuously optimizing lamination parameters is required to achieve good bond quality and ensure that the product’s properties are maintained over its lifetime.
How Does Packaging Prepare Products for Global Distribution?

Frequently Asked Questions (FAQs)
1. What distinguishes SPC flooring from traditional vinyl flooring?
SPC flooring is fitted with a stiff limestone composite core. Thanks to this SPC floor has much better dimensional stability than other typical floor coverings made of flexible vinyl, so-called conventional flooring.
2. Can SPC flooring be installed over existing subfloors?
Yes. Click-lock flooring can be laid straight away over most sub floors without the need for adhesives or time consuming preparation of the sub floor that is required for most other floor coverings.
3. How does temperature variation affect SPC flooring performance?
The dense composite structure has a very small degree of expansion and contraction due to temperature variations. The shape of the structure is retained in the long term.
4. What maintenance practices extend SPC flooring lifespan?
Daily sweeping of the floor and occasional cleaning with damp mops and neutral cleaning products will help protect the surface of the floor from damage. Using abrasive cleaning tools could quickly wear away any protective floor coatings.
5. Is SPC flooring environmentally friendly?
Many manufacturers such as Shandong Lanhe Import & Export Co., Ltd use materials that are recyclable and free from harmful substances like formaldehyde and heavy metals. Eco-certifications are used to verify sustainable compliance throughout their production processes.
