A wide range of machinery manufacturing industry, including transport, machine tools, agricultural machinery, textile machinery, power machinery and precision instruments and other machinery manufacturing, generally speaking, there are casting, forging, heat treatment, machining, assembly and painting and so on, the occupational disease hazard is very significant.
 
Mechanical processing is the use of all kinds of machine tools for metal parts for car, planing, drilling, grinding, milling, cold;General mechanical processing production process of occupational disease hazards are relatively small, mainly used in metal cutting cutting oil emulsion and the influence on workers, due to the high speed machine tool rotation, emulsion splash around, easy pollution skin, can cause folliculitis, acne, and so on.In the coarse grinding and fine grinding process and can produce large amounts of dust.
Machining of these hazards
1, industrial dust: the main existence and casting industry, the green sand preparation, modelling, shakeout, deoxidization process, can produce a high concentration of dust, especially when using a finishing casting sand blasting process, high dust concentration, the quartz harm is bigger, can cause silicosis and caster pneumoconiosis.In the process of machining, in the process of metal parts grinding and polishing, can produce metal and mineral dust, causing grinder pneumoconiosis.Welding welding flux, welding rod and welding material, evaporation at high temperature to produce a large number of welding dust and harmful gases, long-term inhalation of electric welding is a high concentration of dust can cause electric welder pneumoconiosis.
 
2, high temperature, thermal radiation, mainly exists in casting, forging and heat treatment work, foundry furnace, heat drying furnace, molten metal, casting, forging and heat treatment workshop of heating furnace and red-hot metal components have a strong thermal radiation, the formation of high temperature environment. Serious when transporting.
Machining of these hazards
3, harmful gas: melting furnace and furnace can produce carbon monoxide and carbon dioxide, the concentration of the feed mouth often is higher;When phenolic resin as binder such as formaldehyde and ammonia;Heat treatment can produce organic solvent vapors;When plating, can produce nickel chromium acid fog, acid fog, acid mist and cyanide cyanide;When welding, can produce carbon monoxide and nitrogen oxides;When painting can produce benzene, toluene, xylene, etc;All can cause occupational poisoning.
 
4, noise, vibration and ultraviolet and ionizing radiation: mechanical manufacturing process, the use of sand tamping machine, pneumatic tools, all kinds of forging hammer, grinding wheel grinding, rivets, etc, all can produce strong noise and vibration;Electric welding, gas welding, arc welding and plasma welding produce ultraviolet (uv) light, such as improper protection can cause electro-optic ophthalmia.In workpiece inspection process, often use X-ray flaw detection, radioactive sources and such as do not take right protection can cause radiation injury.
Machining of these hazards
5, heavy manual Labour and trauma, burn in the low mechanization degree, pouring and shakeout, blacksmithing is relatively heavy manual labor, even using air hammer and hydraulic press, as a result of the need to transform the workpiece position and direction, manual labor intensity is very large, at the same time to work at high temperature, easy to cause temperature adjustment and change of cardiovascular system.
 
In the machinery manufacturing and casting and forging of trauma and burn rate is higher, more are due to molten iron, steel, iron, iron slag splash;Machining workshop of more eye, finger injuries.Also used in the process of metal cutting coolant for workers skin has a certain influence.

  • Q Are you a manufacturer or a trader?

    A
    We have our own foundry ,forging factory and machinery shop located in Liaoning Province, China.
  • Q What can you do for customer?

    A
    One Stop Service
    1).Manufacturing and supply various machinery parts.
    2). Technical analysis and design 
    3).Factory audit, on-site production supervision, in-time feedback, pre-shipment quality inspection
  • Q How could you commit the product quality?

    A
    1) all our factories were ISO certified. 
    2) more than 50% of New Densen’s products were sold to worldwide top 500 companies 
    which located in North American, Western Europe, and Japan.
    3) New Densen’s QC engineers will do on-site supervision and before EX-work quality inspection. New Densen will issue inspection reports for customers’ approval before EX-work. New Densen will be responsible for its reports and every parts no matter how long sold to customers.
  • Q How long shall we get the quotation?

    A
    Processing time for inquiry: 1-3 working days.
  • Q What's the process of developing a new steel casting product?

    A
    The procedure for new project develop as below:
    1. Technical department analyze the drawings all details 
     
    2.Pattern design and manufacture
     
    3.Casting Process
     
    4.Quality Control inspect the casting parts
     
    5.Issue inspection report for customer to check quality
     
    6. After inspection report approved, Logistics Department help arrange the shipping to customer
