Productivity improvement of washing tables by setting standard time: a case study of stainless manufactories
Productivity improvement of washing tables by setting standard time: a case study of stainless manufactories

The purposes of this research are to study and improve the productivity process of washing tables by setting standard time a case study of stainless manufactories. Nowadays the manufacturers don’t know the production capacity. That leads to the problems of manufacturers’ work control and late product delivery to the customers. The study is proposed to improve work procedures by designing operation process chart (OPC) the setting of operation stations Operation process chart time (OPC TIME) and finding the standard time in product manufacture. As for the operation process and the standard time setting the research revealed that the standard time of welding station in assembly process for the frame table sink tap nozzle high neck sink flick and welding station of all assembly parts were the first the second the third and the fourth respectively. The researchers’ suggestions were to add 2 welding machines and 2 workers in assembly process so as to work more efficiently so that it can decrease the total processing time from 855.24 minutes/set to 645.91 minutes/set or 24.47 % reduction.

This research aims to compare the shrinkage value that limited from manufacturer with the ASTM D955 Standard Test Method
This research aims to compare the shrinkage value that limited from manufacturer with the ASTM D955 Standard Test Method

Comparing the shrinkage values of HDPE 2 – 4 % that limited from manufacturer are as the following: 1. Comparing the shrinkage of 60 X 60 mm. specimen The result showed that there aren’t any shrinkage differences among follow the injection across the injection and the limited value from the manufacturer. 1.1 Comparing the shrinkage of the specimen with 2 mm. thick The result showed that the shrinkage between at the point nearby the entrance is different from at the point further from the entrance and it is also different from the limited value from the manufacturer. 2. Comparing the shrinkage of 12.7 X 27 mm. specimen The result showed that there aren’t any shrinkage differences among follow the injection across the injection and the limited value from the manufacturer. 2.1 Comparing the shrinkage of the specimen with 3.2 mm. thick The result showed that there aren’t any shrinkage differences among the point nearby the entrance the point further from the entrance and the limited value from the manufacturer. 3. Comparing the shrinkage of 100 mm. round specimen The result showed that there aren’t any shrinkage differences among follow the injection across the injection and the limited value from the manufacturer. 3.1 Comparing the shrinkage of the specimen with 3.2 mm. thick The result showed that there aren’t any shrinkage differences among the point nearby the entrance the point further from the entrance and the limited value from the manufacturer. Comparing the shrinkage values of PET 0.2 - 0.4% that limited from manufacturer are as the following: 1. Comparing the shrinkage of 60 X 60 mm. specimen The finding revealed that the shrinkage value of the follow injection is different from the across injection but it is not different from the limited value from the manufacturer. 1.2 Comparing the shrinkage of the specimen with 2 mm. thick The finding revealed that the shrinkage value between the point nearby the entrance and the point further from the entrance are different but the same as the limitation from the manufacturer. 2. Comparing the shrinkage of 12.7 X 27 mm. specimen The finding revealed that the shrinkage value of the follow injection is different from the across injection but the same as the limited value from the manufacturer. 2.1 Comparing the shrinkage of the specimen with 3.2 mm. thick The result showed that there aren’t any shrinkage differences among follow the injection across the injection and the limited value from the manufacturer. 3. Comparing the shrinkage of 100 mm. round specimen The finding revealed that the shrinkage value of the follow injection is different from the across injection but it is not different from the limited value from the manufacturer. 3.1 Comparing the shrinkage of the specimen with 3.2 mm. thick The finding revealed that the shrinkage value of the follow injection the across injection and the limited value from the manufacturer are the same. Both comparing HDPE and PET have statistical significance at 0.05

Development of the Apparel Product Style from Teen Chok Fabric Mae Chaem District, Chiangmai Province for Local Product Standard
Development of the Apparel Product Style from Teen Chok Fabric Mae Chaem District, Chiangmai Province for Local Product Standard

The purpose of this research was to development of the apparel product style from Teen Chok Fabric of Mae Chaem District in Chiangmai province and technology relay of the apparel product development for the target group. This research managed by the survey the design the analyze the prepare a apparel pattern the apparel pattern evaluation the target training the training management and the analytical information. The research result were the nine apparel patterns that were decorative casual apparels with Teen Chok Fabric. The technique used patchwork patches gatherings and fillings etc. The opinion of the interested groups in the apparel pattern and evaluation were blouse pattern D B and I were the highest suitable in both patterns and decorations. The participants found that the community group participants in Chang Choeng Village of Mae Chaem district in Chiangmai. Before they were trained they had known in a few design the sewing and the decoration in medium level. After they had been training they know three parts in high level and they would require the next training in the highest level. The average were good level.

การหลอมภาพให้มีความคมชัดสูงแบบพีซีเอด้วยเทคนิคการแปลงเวฟเล็ต

Currently the edge image is regarded as important in the process of digital image processing. Because in the field of image processing in certain fields require lines or the edge of a complete description of the image in the photo itself. It is also essential to engineering. Most commonly used to calculate the difference like testicle to calculate the area between the point-to-point. Applied to select the coefficients to be used in combination with a new edge image clarity of the picture more. In this research will be trimming the edge blending image to compare the quality of the image obtained by the theoretical conversion web Paulette (Wavelet Transform) to demonstrate how to mix the new image it can provide the sharpness of the image the better. The assessment found that the proposed method can increase the contrast of the image. And maintaining data within the output video in its entirety
