Blow mould plastic manufacturing is the process through which hollow plastics are made. The process begins with the melting of plastic leading to formation of a substance known as "parison." Parison is a tubelike plastic with a hole on one side. When air is compressed, it passes through this hole. The parison is clamped into a mould before air is pumped in, which makes the plastic match the mould.
The process of blow mould plastic manufacturing involves the use of various types of heavy machinery which make a lot of noise in the factory. Sometimes the level of this noise can present a danger to the people working in the factory. High noise level can have a negative effect on peoples' ears. In extreme cases, it can cause noise-induced hearing loss.
Plastics are hazardous to the environment since they are not biodegradable. Their unsafe disposal in the environment presents a hazard especially when empty plastic containers are dumped in landfills or just thrown away in the open. When the plastic materials are disposed in landfills, they end up being buried under the ground where they might remain forever unless they are burnt. Plastics also risk the lives of organisms which live in the soil.
Dependence on Petroleum
A lot of petroleum is used In the process of making blow-moulded products. Since oil is the most important agent in thermoplastics, the process contributes to the diminishing of an already declining commodity. The petroleum ingredient also makes plastics more vulnerable to fire. If a fire breaks out in these manufacturing plants, it can spread very quickly.
Very high temperatures are used during the production process of plastics. If the injection parts are easily accessible, they should be guarded or be insulated. This is necessary in order to prevent contact with these surfaces which can be dangerous to the people working in the factory.
