This paper describes an aluminum casting jewelry manufacturing because of the current manufacturing costs are higher. Material or metal that is commonly used to cast jewelry is silver which aluminum Alternatives to metal. Melting is There is a close color and surface finish can be beautiful. But aluminum is a material that is cheap has studied and tested. Replacement aluminum casting body jewelry. The temperature in the baking mold before casting to test all five temperatures are 550 500 450 400 350 degrees Celsius then casting body jewelry in the next stage of the research process casting jewelry with the. aluminum to Experimental temperatures used in baking mold casting plaster for the mold temperature of 400 is appropriate. Best of casting jewelry with aluminum. The results showed that there is minimal waste and a 102 pieces of 48 pieces and has a smooth surface. A similar performance to the other materials available. Similar properties

Thailand’s gem and jewelry industry is widely considered one of the greatest potential markets in the world. One of the important processes is producing the body jewellery or casting. The lost-wax castingtechnique is a popular technique used widely. However it can also be a source of many defects such as porosity tarnishing incomplete form filling and water stain. There is not finding causes of problems affecting the cost of production labor energy and time increased. This research aims to study the production problems and deficiencies of work piece in the actual work from10 casting industriesto identifying and preventing all these problems. This study will be helpful to entrepreneurs gems and jewelry industry to use as guidelines to prevent defects reduce waste reduce production costs and improve the casting process for the piece even more quality. The study found that most of the production process is the main the machinery / equipment and material problems the problem of secondary respectively by this process the main problem is the casting and foundry molds the injection and the candles prototype and mold making rubber the order is a minor respectively work piece for defects in castings are very common a flaw was found in the specimens I have a 6 specimen defects found in wax and defects found in rubber molds and prototypes the defect occurs in each style be caused by a wide variety of cases. Problems encountered in this study the most hole of the shrinkage problem problem of casting porosity the hole of the bubble the cracking problem the cast is not full the problem is the ceiling.

The objectives of this research are to use waste silk yarn for making women accessories and transfer the created technology to a women community in Surin Province. The required information for product design was collected. Subsequently 15 conceptual designs were made including necklace bracelet and bangle earring and pin. The experts were asked to choose the best 5 designs out of 15 designs. Then the prototypes were made by using waste silk yarn. Finally the most suitable product was selected for further technology transfer to a target group of 55 women who live in Surin. The questionnaires were used to asses the satisfactory of the training. The corresponding data was statistically analyzed. The results from the evaluated questionnaires show that most of the attended women are 31–40 years old and graduated from lower secondary schools. They are merchants and their average earnings are below 5000 Baht/month. Regard to the training program in terms of preparation instructors and overview most of them are satisfied the program in the high level to very high level. The average satisfactory for all of 3 aspects is in the high level.

This study was an aim to apply lacing technique to produce yarn accessories for value added and developing the new products. It was a survey research by questionnaires tool. The study was divided into 2 steps. The first was collected the basis data for product analyzed and appropriate design to produce the prototype products. Thai traditional design was chosen to master design prototype as kanok naree kacha and krabi traceries. All of these traceries are gentle and shown as the Thai design. Kanok is a thai traditional style that it was chosen for a represent design and combine together with product design and decoration trend on 2013-2014 in Formal & Sugary style. The prototype products 7 collections: necklace earring and brooch. The prototype products were accepted from the sample group which they were very good in the factors of the beautiful technique the utilization and the quality of products. The prototype had price in range 801 – 1 300 Bath. The prototypes were adequate detail. From these results the prototypes were response with customer and make an alternative choice to increase the household income.

The research aimed to analyze jewelry in various forms such as necklaces bracelets rings and earrings as well as to apply knowledge to develop jewelry with stamping techniques by using metals silver and synthetic gemstones. The data of the research was obtained from the interview the analysis of jewelry forms for producing an jewelry prototype and the satisfactory evaluation. The results of the research were that the most of modern jewelry had natural shapes. However they had few manmade patterns. The patterns mostly came from the colors of the gemstones. Silver was used as a material of the whole jewelry ring. As work creativity it was found that most modern jewelry production was based on wax mold prototype molding rubber mold press wax injection molding finishing plating and stone decoration. The result of the research brought to the design for developing better jewelry forms. The process of the design consisted of studying design theories and creating various jewelry forms. As the evaluation by the experts the design with natural shapes obtained the highest rate of evaluation (the second form). The second highest one was the seventh form which was the contemporary jewelry with beautiful gemstones. This one was suitable for jewelry prototype production with stamping techniques by using paper clay ceramic for satisfactory evaluation the consumers were satisfied with the jewelry made of paper clay ceramic with the rates of much and the most. This was consistent with the research hypothesis i.e. to obtain modern forms of jewelry made of paper clay ceramic which were used as a guideline for creating and developing modern jewelry forms according to the customer’s needs and for developing materials for innovation which could reduce production cost and time of the manufacturers.
