WAXING DEPARTMENT
It is a department that is responsible for forming products to match the pattern that is defined in a sub-job card, suitable for workpieces that cannot be produced in the form of pressing process (stamping work). This sub department is in the first process and is specified in the sub-job card received from the Pre-production department, Waxing process begins as follows:
WORKING PROCESS
-
Employees who received the Sub-job card will begin to print the mold by using wax as the main raw material for forming, which is becoming more popular in the casting process for mass production.
-
Rubber mold making: The rubber mold will be made to cover the product template. In the construction of the rubber mold, the mold is placed in a frame and is fastened with a special rubber sheet placed in the rubber mold press (Vulcanizer) which is a machine that uses heat and pressure to compress the rubber to flow all around the mold.
-
Wax workpiece or wax copying: It is copying the product out of the mold. The heated wax is injected into the rubber master mold flows through a narrow hole to fill the space inside the mold that takes less than a minute. After that, the workers will wait to cool down wax workpiece and ready to be removed from the mold.
-
3. Bring the mold to be attached to the main base to become a tree mold to be cast in the next step.
4. Then the worker will weighing the mold and bringing it into the casting process.
RELATED STRATEGIES
Mass production: the manufacture of large quantities of standardized products, frequently using assembly line or automation technology. Mass production refers to the production of a large number of similar products efficiently and typically is characterized by some type of mechanization to achieve high volume, detailed organization of materials flow, careful control of quality standards and division of labor.
Advantages
-
It is usually 'automated' to the highest extent possible.
-
Fewer labor costs
-
Faster rate of production
-
Capital and energy are increased while total expenditure per unit of product is decreased
-
Faster rate of production
Disadvantages
-
Machinery is very expensive to buy, so production lines are very expensive to set up.
-
Workers are not very motivated, since their work is very repetitive.
-
Not very flexible, as a production line is difficult to adapt.
-
If one part of the line breaks, the whole production process will have to stop until it is repaired.
Economies of scale: refer to reduced costs per unit that arise from increased total output of a product. For example, a larger factory will produce power hand tools at a lower unit price, and a larger medical system will reduce cost per medical procedure.

Types of Economies of Scale
-
Internal Economies of Scale
A result of the sheer size of the company. It doesn't matter what industry it's in or market it sells to. For example, large companies have the ability to buy in bulk. This lowers the cost per unit of the materials they need to make their products. They can use the savings to increase profits. Or, they can pass the savings to consumers and compete on price.
​
2.External Economies of Scale
A company has external economies of scale if its size creates preferential treatment. That's most often occurs with governments. For example, a state often reduces taxes to attract the companies that provide the most jobs. Big real estate developers convince cities to build roads to support their buildings. This saves the developers from paying those costs. Large companies can also take advantage of joint research with universities. This lowers research expenses for these companies.
The factory can use the internal economies of scale because of the factory has a bargain power of suppliers it means they can buy materials in bulk that makes the cost of products low and the factory can save its cost. For the external economies of scale, the factory's products which export to aboard are exempt from export tax and vat because Thai government has a policy to attract the foreigner investors to make a trade in Thailand.
