Artificial Culture Stone Making Machine
Longqi Artificial Culture Stone Making Machine is a type of industrial equipment used to produce artificial (man-made) stone veneers, also known as cultured stones, which mimic the appearance of natural stone for use in architectural and decorative applications.
Our machines are designed to cast and mold concrete, gypsum, or resin-based materials into textured stone-like products, using flexible or rigid moulds, vibration, coloring, and curing systems.
What is Artificial (Cultured) Stone?
Artificial culture stone is a lightweight, cost-effective decorative product made from:
Cement + sand + lightweight aggregate + pigment (for concrete-based)
Gypsum + pigment (for interior use)
Resin + fillers (for ultra-lightweight versions)
It simulates the look and feel of real stone (slate, sandstone, granite, etc.) but is easier to install and customize.
Main Applications of Artificial (Cultured) Stone
Exterior Wall Cladding
Used on building facades, house exteriors, and boundary walls
Enhances aesthetics with a natural stone look
Often replaces brick or natural stone due to lighter weight
Interior Wall Decoration
Used for feature walls in living rooms, hotel lobbies, restaurants, etc.
Suitable for fireplaces, TV backdrops, or reception areas
Offers a textured, rustic, or modern look
Landscaping and Hardscaping
Garden and pathway walls
Planters, fountains, retaining walls
Outdoor seating and decorative elements
Commercial Buildings
Shopping malls, office complexes, and entertainment venues
Used for pillars, facades, interior partitions
Public Infrastructure
Subway stations, railway terminals, government buildings
Aesthetic stone appearance with improved cost control
Urban Furniture & Elements
Street planters, benches, signage panels, fencing
Consistent design across city infrastructure
What is an Artificial Culture Stone Making Machine?
A machine or production system that automates the process of producing cast-stone veneers by:
Mixing raw materials
Pouring into stone-textured molds
Vibrating and compacting for surface detail
Curing the product
Demolding and coloring (if applicable)
Components of an Artificial Stone Making Machine
| Component | Function |
|---|---|
| Mixing Unit | Batches concrete or gypsum mix with pigments |
| Vibration Table | Vibrates filled moulds to settle material and form texture |
| Stone Moulds | Silicone/PU/rubber molds with stone texture patterns |
| Color Spraying System | Applies surface pigments, oxides, or stains |
| Curing Chamber or Racks | Cures stones under heat or ambient temperature |
| Demoulding Station | Ejects stones from moulds (manually or mechanically) |
| Conveyor / Handling System | Moves moulds through production line |
Manufacturing Process
Raw Materials Typically Used
White cement / Portland cement
Quartz sand or lightweight aggregates
Iron oxide pigments
Additives (plasticizers, waterproofers)
Water or resin binder (for some systems)
The manufacturing process of Artificial (Cultured) Stone using a Culture Stone Making Machine involves a step-by-step production line designed to replicate the texture and appearance of natural stone using molds, pigments, and cement-based or gypsum-based mixtures.
Below is a detailed explanation of the entire process, from raw material preparation to finished product output.
1. Raw Material Preparation
Materials typically used:
White Portland cement / gypsum
Quartz sand / fly ash / lightweight aggregate
Iron oxide pigments
Water
Additives (plasticizer, water reducer, waterproofing agent)
Key Equipment:
Dry material storage silos
Automatic dosing system
Powder/pigment feeders
2. Mixing
Purpose: Create a homogeneous mixture of cement, sand, pigment, and additives.
Process:
Ingredients are fed into a planetary or pan-type concrete mixer
Add water gradually to control workability
Ensure color and consistency are even
Time: 5–8 minutes per batch
3. Mold Filling / Casting
Process:
The mixed slurry is poured into rubber, PU, or silicone molds fixed on a vibrating table
Moulds replicate the shape and surface texture of natural stone
In automatic systems, mold-filling machines or pouring robots are used
Note: Surface coloring can be sprayed before or after filling
4. Vibration and Compaction
Purpose: Remove air bubbles, improve surface finish, and settle material into mold details
Method:
Vibration table or compaction platform vibrates the molds for 30–60 seconds
Ensures sharp stone texture and prevents surface defects
5. Surface Coloring (Optional)
If not mixed with the base color:
A spray gun or hand sponge applies iron oxide pigments, stains, or color hardeners
Can simulate multicolored or aged stone surfaces
6. Initial Curing
Purpose: Allow the product to harden enough to be removed from the mold
Conditions:
Room temperature (20–30°C) and >75% humidity
Steam curing chambers can accelerate to 4–8 hours
Without steam, it usually takes 12–24 hours
7. Demolding
Process:
Cured stones are carefully removed from the mold
Demolding can be done manually or with a mechanical ejector
Mold care: Apply mold release agent to extend life (especially for PU or silicone molds)
8. Final Curing / Drying
Purpose: Complete strength development
Methods:
Air curing racks (7–14 days in ambient conditions)
Steam or hot air chambers for high-volume production
This step is critical for outdoor-grade stones
9. Surface Finishing (Optional)
Options:
Brushing or sanding for antique effect
Sealant application to enhance water and UV resistance
Inspection and grading for quality control
FAQs
What materials are best for outdoor stones?
Use cement-based mixes with iron oxide pigments, fiber reinforcement, and water repellent additives for durability and colorfastness.
What are the common mould materials?
Silicone molds: High detail, flexible, long life
PU (Polyurethane): Flexible, affordable
ABS/Plastic: Rigid and cheap, but lower detail
Fiberglass: Durable for large moulds
How many stones can I produce per day?
Depends on mould quantity and machine type:
Manual: 500–1,000 pcs/day
Semi-auto: 2,000–4,000 pcs/day
Full auto: 5,000+ pcs/day
How long does curing take?
Normal curing: 24–48 hours
Steam curing: 6–12 hours (accelerated)
Must maintain humidity and temperature to avoid cracks or weak texture
How long do moulds last?
Silicone/PU: 500–1,000 cycles with care
Plastic: 200–300 cycles
Is coloring applied in the mix or after demolding?
Integral coloring: Pigments added into the mix
Surface coloring: Sprayed or hand-applied after casting
Many use both for realistic stone effect
Can I make both interior and exterior stones with one machine?
Yes — with different mixes and curing conditions. Use cement for exterior, gypsum for interior (less weight, not water-resistant).
Can these machines make 3D wall panels or brick textures?
Yes — simply by changing the mould. Popular textures include:
Ledge stone
Fieldstone
Brick veneer
3D geometric designs
How much space is needed for a small factory?
Small setup (manual): 100–300 m²
Medium (semi-auto): 500–1,000 m²
Full automatic: 1,500–5,000 m² with curing and packing area
