- How Iron Cover Are Made: In Factory Mass Production | Manufacturing Process | Cast Iron Covers
1. Cast Iron Covers
**A. Pattern Making:
Design: Create a detailed design and pattern of the cover. This could be done using CAD software to ensure precision.
Pattern Creation: Produce a pattern, typically made of wood or plastic, which will be used to form the mold. The pattern represents the exact shape and dimensions of the final cover.
**B. Mold Preparation:
Sand Molding: Create a mold using sand casting. The pattern is pressed into a sand mixture (often mixed with a binder) to create a cavity in the sand.
Mold Assembly: The sand mold is then assembled and prepared for the casting process.
**C. Melting and Pouring:
Melting: Cast iron is melted in a furnace at high temperatures (approximately 1,400°C or 2,550°F). This involves heating pig iron, scrap iron, and alloys.
Pouring: The molten iron is poured into the prepared sand mold. The metal fills the cavity left by the pattern, taking the shape of the cover.
**D. Cooling and Removal:
Cooling: Allow the cast iron to cool and solidify in the mold. This process can take several hours.
Mold Removal: Once cooled, the sand mold
removed to reveal the cast iron cover.
**E. Finishing:
Cleaning: Remove any sand or residues from the surface of the cover.
Machining: Perform any necessary machining to achieve precise dimensions and surface finishes.
Painting or Coating: Apply protective coatings or paint to prevent corrosion and enhance durability.
**F. Inspection and Testing:
Quality Control: Inspect the cover for defects, measure dimensions, and conduct strength tests to ensure it meets specifications.

I hope these guys get to trade off on jobs. Talk about repetitive boredom! Anyway these guys work hard to support their families. Good job guys from Southern California USA
Trabalhei na área de engenharia, no desenvolvimento de novos produtos. Posso dizer que conheço um pouco das exigências técnicas e de qualidade aos quais os produtos são submetidos. Entre outras necessidades, há normas, especificações, exigências qualitativas e padrões técnicos a serem atendidos.
Não consigo imaginar como que esse produtos, confeccionados de forma totalmente rudimentar, num ambiente inseguro e aparentemente sem nenhum tipo de controle chegam ao mercado.
Impressionante como trabalham, produzem... Sem qualquer sofisticação, embora em um ambiente com alto risco de acidentes, sem o uso de EPI.

Good Morning!
nice video
Nunca supe para que se utiliza o para que hicieron eso 🤔🤔 pense que eran planchas
How are they used?
Sir location kya he
That's not mass production by today's standards. All the handling to cut, shape, mold and punch all the holes could be done by a single machine within a second.
All the cleaning, plating and do ffg worth could be done in another automated setup in a few minutes.
This would all untouched by hands.
Why do they cover & uncover them with sand?
It's probably not sand. I'm guessing it's some sort of absorbent material to remove the excess of the fluid they had just applied before.
But I could be wrong.
Sawdust, to remove the oil they covered them with for pressing.
Year in year out the same work
That's the same all over the world. Unless you're highly educated, you do repetitive jobs.
