Are you planning to enter the profitable stationery market or looking to scale your current production? Finding the right equipment is the first step toward success. Whether you are searching for a competitive chalk making machine price to fit your startup budget or looking for a high-capacity chalk making machine for sale to upgrade your factory, our newly upgraded automated models offer the perfect balance of efficiency and quality. From dustless technology to custom shapes, here is everything you need to know about optimizing your production with our advanced machinery.
Can the Fully Automatic Chalk Making Machine Produce Colorful or Scented Chalk?
Ja, the machine is fully capable of producing both white and colorful chalk. By adding water-soluble pigments or color powders during the electric mixing stage, you can achieve vibrant, uniform shades. The automated stirring system ensures the color is blended thoroughly, eliminating the streaks or uneven tones often found in manual production. This allows you to easily manufacture rainbow sets or specific branded colors to meet diverse market demands.
What Is the Output Capacity of the Chalk Manufacturing Machine?
The fully automatic chalk making machine’s output is highly scalable to suit any business size, offering a production range from 2000 aan 32000 pieces per hour for standard models, and up to 90000 pieces per 8-hour shift with our heavy-duty industrial units. By utilizing high-capacity molds that produce 800 pieces per cycle alongside an automated assembly-line system, you can easily switch between single-mold setups for small workshops or multi-mold configurations for mass production, ensuring maximum efficiency and stable supply regardless of your project’s scale.
What Is the Working Process of a Chalk Making Machine?
Mold Pre-treatment (Smering)
Apply a uniform layer of release oil inside the mold holes using a wide brush. For new molds, ensure a more generous application to guarantee a smooth finish and effortless demolding.
Mechanical Alignment
Cycle the mold plate up and down a few times to ensure the top of the screw is in firm contact with the bottom of the mold, preparing the unit for filling.
Precise Water Supply
Activate the foot switch to supply water, depressing the pedal fully until the water level covers the mold. (Always follow the sequence: Prepare the mold and materials first, then add water.)
Materiaalvoeding
Add the pre-measured quantity of high-quality gypsum powder into the mixing bucket.
Power Mixing
Start the motor and engage the high-speed electric stirring system for 10–20 seconds to ensure a completely smooth and homogeneous slurry.
Slurry Grouting (Filling)
Open the discharge switch to pour the well-mixed slurry into the mold holes. Ensure the slurry flows steadily until all molds are completely filled.
Surface Scraping & Leveling
Use a professional plastic scraper to level the top of the mold holes, removing any excess slurry to ensure the base of each chalk is neat and flat.
Efficient Demolding
Once the chalk has set and feels slightly firm (timing is key for new molds), eject the chalk by 2–5 mm first. Wait 1–2 minutes before performing the final ejection/demolding.
What Is the Ratio of Gypsum Powder to Water for Making Chalk?
The standard golden ratio for making chalk is 2:1 by volume (2 parts gypsum powder to 1 part water). This ratio creates a slurry with a consistency similar to thick yogurt, providing enough fluidity to fill every detail of the mold while ensuring the finished chalk is durable and resistant to breaking.
In practice, it is recommended to use the “water first, powder second” method—adding the powder to the water—to allow for better absorption and minimize air bubbles. If you are aiming for dustless quality, you can add about 10% white glue (PVA) to the water as a binder; this increases the chalk’s density, causing particles to fall straight down due to their weight rather than floating in the air.
Does the Fully Automatic Chalk Making Machine Require Drying Equipment?
Nee, specialized drying equipment is not strictly required to start your production. Once demolded, the chalks can be dried naturally by placing them in a well-ventilated area or under direct sunlight, which is a cost-effective solution for small-scale workshops.
Egter, for commercial or mass production, we recommend using a drying box or drying room. This speeds up the process significantly, allowing you to move from production to packaging in a fraction of the time. Using drying equipment also ensures consistent quality regardless of weather conditions, preventing issues like moisture retention or cracking during humid seasons.
Can I Customize the Mold Design or Chalk Size?
Ja, absoluut. While we provide standard molds, we also offer full customization services for both chalk dimensions and shapes to help your brand stand out. Whether you need specific lengths, diameters, or unique geometries like round, vierkantig, hexagonal, or triangular designs, our engineering team can tailor the molds to your exact requirements, ensuring you can produce everything from standard classroom supplies to specialized jumbo sidewalk chalk.
