How is a color pen made
Answers
Answer:
The process begins with PPC pellets being separated, measured into the right portions, and poured into a giant funnel known as a hopper. The plastic pellets travel through a machine where they're melted down and injected into molds in the shape of the pen barrels.

Answer:
Making the ink:
1 The ink mixture is concocted. Preferable ratios are 1-10 % water by weight (the water content must be sufficient for complete dissolution or dispersion of the dye), with the remainder of the weight being made up of a solvent such as alkyl or alkylene carbonate.
2 Conventional additives, such as nonylphenylpolyglycol ether, alkylpoly-glycol ether, fatty acid polyglycol ester, or fatty alcohol ethoxalates, and preservatives, such as ortho-phenolphenyl and its sodium salt, ortho-hydroxydiphenyl, or 6-acetoxy-2,4-dimethhyl-m-dioxane, may also be added to the mixture.
Making the marker:
3 To make the body of the marker, plastic resin is injection-molded into a marker body. Injection molding involves heating a substance, in this case plastic resin, into a molten state and forcing (injecting) it into a mold of the desired shape, then allowing it to cool and harden. Marker caps and plugs are formed in the same manner as the barrel.
4 The nib, or tip, of the marker is made from powder which is mixed with water, molded, and baked into its pointed or flat form.
5 Using one machine for all the following functions, an assembler then places a polyester cylinder inside the marker barrel to form a reservoir for the ink, fills the reservoir with ink, and inserts the nib at the bottom and the cap at the top.
6 The markers are then placed into color assortment and packaged for retail marketing.
