• Raw material.- Accounts for 60 – 80 % of total cost of tank.
• Optimizing the weight of Tank.
• Double and Triple Layer Tank.
• How to get Uniform Distribution of Material during process. X-Y ratio, Mould Design, Powder Quality,
• Reduce Rejections by Power Failure etc.
Raw Material.Raw Material.
• Convert to LPG or Natural Gas if viable.• Select Correct Machine Size.• Make Small Tank of Small Machine or Multiple Mould
Mounting. • Keep burner tuned for efficiency. Clean filter, Nozzel,
replace pump if pressure is below 8 Kg/cm2.• Switch off burner before cycle time ends.• Keep Lowest possible moulding temp.
Fuel.Fuel.
• Electric Power.• Extrusion, Pulverizing & Moulding.• Extrusion - Use higher capacity- Gas Heating – Higher batch size.
Measure Power Consumption regularly.• Pulverizing – Use higher capacity - Measure Power Consumption
regularly. • Rotational Moulding – Use as small machine as possible, or run
multiple moulds. Switch off re-circulating blower. Use Mist Cooling fan or Air Cooler.
• Remove Tank in Hot condition.
Electric Power.Electric Power.
• Good Shop-floor Layout.• Use higher capacity machines, like EN-1000x2 or Three
Arm.• Cultivate Habit of multi-tasking.• Maintain Motivated work culture.
Manpower.Manpower.
• Eliminate Wastages & Breakages.• Keep track of replacements.
Lid & Fittings.Lid & Fittings.
• Optimize Order Quantity.• Develop transport contractors.• Purchase transport vehicle depending on your business.• Don’t concentrate on long distance market at the cost of local market.
Transportation.Transportation.
• Keep functioning of factory very simple.• Keep minimum staff. • Utilize existing staff to maximum by making them responsible.
Believe in your people.• Regular Preventive Maintenance of machines
Overhead.Overhead.
• Keep Record of Rejections.• Wastages during Extrusion.• Wastages during Pulverizing.• Rejection because of Power Cuts. Keep Backup Generator.• Study market rejections.
Rejections.Rejections.
• Fittest will only survive and Grow in long run.• Focus on every aspect of cost reduction Don’t neglect small
savings.• Use latest technology, methods.• Invest in energy efficient technology.• Keep track of Rejections.
