The inner surfaces of a concrete mold are greased with oil to create a smooth release surface, preventing the concrete from sticking to the mold when it sets. This lubrication facilitates easier demolding, reducing the risk of damage to the concrete structure and the mold itself. Additionally, it helps to achieve a better surface finish on the concrete by minimizing imperfections that may arise from friction during the removal process.

How do you achieve slump in concrete?
The mould is placed on a smooth, horizontal,rigid and non-absorbant surface The mould is then filled in four layers, each approximately 1/ 4 of the height of the mould.Each layer istamped 25 times by the tamping rod taking Slump Test Apparatus care to distribute the strokes evenly over the cross section.After the top layer has been rodded, the concrete is struck off level with a trowel and tamping rod. The mould is removed from the concrete immediately by raising it slowly and carefully in a vertical direction. This allows theconcrete to subside. This subsidence is referred as slump of concrete.The difference in level between the height of the mould and that of the highest point of the subsided concrete is measured. This difference in height in mm is taken as Slump of Concrete.
What is the mass of metal cast into a mold and ready for recasting?
A mass of metal cast into a mould is called either an ingot mould or a cold mould. the one that is ready for recasting is usually the ingot mould. A cold mould is one that has been cast on design that maintains its mould.
Why plastics injection molds are so expensive?
Before making the mould, we need to do the product design and mould design, then according to the cliects' requirement, we need to prepare the mould steel, some steel is expensive, some is cheaper, it is depened on client. During making the mould, we need to tool the mould, which will costs lots of labour cost and tooling costs. if tyhe mould has some problem, we also need to modify it, is is also a rxtra cost.
How do you quote an injection mold?
To quote for an injection mold, first you need check the sample or product design to know the mould structure. Then you calcuate mould steel cost, labot cost, tooling cost. then you add all cost togther. Looking for plastic mould supplier, pls send details to: mould@sinomould.com

Yes, mould reproduces by releasing spores into the environment. These spores can travel through the air and land on surfaces where they can grow and form new mould colonies under the right conditions.
