Increasing the production capacity of refrigerators and freezers in Goldiran Company

Approach planning, project planning and implementation of methods to improve and increase production of Goldiran refrigerator and freezer factory
In this industrial and production unit, the main objective of the Goldiran company can be considered to be the increase in production capacity. It is the fundamental responsibility of the production manager of the Goldiran company to achieve the quantitatively desirable targets. If the Goldiran company does not face any obstacles in the increased sale of its products in the market and there is sufficient demand for the products produced by the organization, the way forward for a slight increase in production through the Increasing sales is easy. can be used to improve the resources, capabilities and capabilities of the organization, and to implement plans and methods to improve and increase production and sales.

Technically, increasing the level and volume of production can be achieved through the following ways and methods. We divide measures aimed at increasing the volume of production into one type of classification into physical and material methods and methods to improve efficiency and improve productivity. Specific actions can be listed for each of these two types of approaches. These actions are possible means, to choose and act according to them, the necessary analyzes and investigations must be carried out to determine which method is most suitable for the existing conditions and characteristics.
A- Methods for improving and increasing production with material measures
The means of this approach are to estimate and prepare the resources and physical facilities necessary to increase the volume of production. As you know, the resources required for production, including devices and machines, raw materials, labor, working space and environment, equipment, tools, etc. . . are. Naturally, material methods that include the following seek to increase each of the resources to create more capacity and production possibility.
1- Increase the shift
2- Purchase, installation, commissioning and operation of new production lines
3- Increase the number of workers, for manual and energy-intensive processes
4- Change production technology, purchase new machines with more modern technology, volume, quantity and speed of production
5- Use subcontracting services and outsource production activities
B- Increase production by improving efficiency and promoting productivity
1- Reduction of production line stoppages
2- Resolve quality issues
3- Reduce scheduled shutdowns due to production line changes or mold changes
4- Improve the productivity of human resources
5- Improve the ergonomics of production activities
6- Change and improve production processes
7- Improve transportation systems and move materials, parts, products and tools
8- Make the activities of device setup, tool setup such as molds and accessories, and placement of parts, materials and products error free.
9- Automation and automation of production activities, movement and transport between workstations and the different stages of production.
The approach of Goldiran Industries refrigerator and freezer factory has been to increase production capacity by improving efficiency and productivity (by changing and improving production processes).
Increase production by improving efficiency and improving productivity
Steps taken at Goldiran Industries refrigerator and freezer factory to reduce cooking time
1- Modification of the quantity of raw materials used 2- Modification of the stoichiometric ratios used of raw materials 3- Installation of a fan to evacuate air or vent in the foam 4- Modification of the structure of the machine to improve the foam injection 5- Adjustment and control of raw material temperature 6- Adjustment and control of mold temperature 7-Adjustment and control of preheating temperature
Reduce the curing time of polyurethane foam
The most important role of hard polyurethane foam in household appliances such as refrigerators is to create a high-performance, energy-optimized thermal insulation system. The closed cell structure is considered the most important feature of this category of foams, which provide poor thermal conductivity and the best insulation performance. Polyurethane cooling foam is injected as an insulating material between an outer layer of metal and an inner layer of ABS. The high adhesion properties of polyurethanes provide a tight bond between interior and exterior walls and help prevent heat exchange. Generally speaking, in the production of molded polyurethane foams for refrigerators, the goal of a craftsman or a manufacturer of household appliances is to reduce the time the refrigerator foams come out of the mold, because under these conditions, the speed of production increases, which is economical. for the manufacturer. The raw materials used, the type of machine used and the speed of the production process are effective on the unmolding time of refrigerated foams. In the discussion of raw materials, the formulation of raw materials can determine the time of release from the mold.In some formulations, the reaction speed is faster and the foam cure time is shorter, resulting in faster demolding.

    

In some other formulations, the reaction rate is lower, which also results in a longer demolding time. The stoichiometric ratios used in the production line are very important. Because it affects the curing stage of the foam. If the foam curing process is carried out at high speed, the residence time in the mold will also decrease. In the formulation discussion, the isocyanate/polyol ratio used is very important. If this ratio is not respected correctly and is above or below a certain amount, the result will be opposite and should have an optimal limit. Because thanks to the reaction of the isocyanate functions with the polyol, if the stoichiometric ratios are correctly observed, we will obtain the best reaction. The research and investigation on the elements mentioned above has allowed us, in a refrigerator model to high temperature foam volume, thick walls, best chemical reaction, highest quality and 60 seconds reduction in foam curing time. Reducing the foam cure time by 60 seconds resulted in 50 units per day, 1,250 units per month and 15,000 units to be produced annually for this model.
