Machinery And Equipments Needed
Chalk Mold: This is the major equipment used for chalk Production it is either rubber or metal but it is usually with a wooden frame, but are chalk made of metal. The mold differ depending of the numbers of hole they have, some could have up to 240 holes or more.
Scrapper: Scrapper is used for scrapping the surface of the chalk mold
Paint Brush: Paint Brush is used to apply lubricants on the mold before filling it up with POP
Dryer: Dryer is used to dry the chalk after it as been removed from the mold, the dryer is electrically operated and is mostly used in large scale production, but for small scale production using the sun is perfectly okay to save cost.
Hand Glove: Hand glove is used for protecting the hands during the mixture of water and POP
Packaging Materials: Packaging Materials is the nylon and branded cartoons and box needed.
Step 1 – Pour some POP into a bucket add water then use your hand to mix it until it forms a paste.
Step 2 – Use the paint brush to lubricate the surface of the chalk mould properly. You can use cooking oil as lubricant, and together lubricate the POP, the stick, and the mold.
Step 3 – Arrange the mold then turn the pasty mixture into the mold and allow it for 15- 20mins to solidify before loosening the mold.
Step 4 – When you are sure that the mixture is formed, loose the mold and collect the chalk produced for sun drying or through mechanical means.
Step 5 – After sun drying for 2-3 days, pack the chalk into a branded carton packs and your school chalk is ready…
I hope with these few information you will be able to start your own chalk production business. Let’s hear from you.
