Abstract

Wax injection machining is the only technique to produce many ideal products in large volumes, which is the most common method in the investment casting process. One of the products that has the highest number of orders in metal casting companies using investment casting techniques is the pump casing VS 2/4/6 X product. The VS 2/4/6 X pump casing product consists of 4 components, each of which is injected into a different mold and eventually assembled into a product. Some of the problems encountered in the wax pattern injection results are dimensional accuracy and product defects. Some parameters that will be analyzed for dimensional accuracy and product defects are injection time, injection pressure, and holding time. This research uses response surface method with 15 run orders with 3 replications and applies Box-Behnken Design for research experimental design and ANOVA to analyze the data. Based on the analysis results. It was found that the optimal parameter combination is the value of injection time of 80 seconds, injection pressure of 35 bar, and holding time of 50 seconds. From this configuration, the dimensional accuracy value is 146.230 mm.

Abstract

The process equipment for the Bananas Getuk machine production, which initially used manual and hand tools, began to be developed for production machine designs, including a mixer machine and a banana Getuk molding. The Bananas Getuk Mixer and Molding Machine used today needs fixing in production. Namely, there is still dough left in the machine, and there are detached components. This problem has an impact on the ineffectiveness of production time and costs. This study aims to analyze the design of the machine by utilizing the DFMA method. The DFMA method provides an assembly process efficiency index (DFA Index) and recommendations for design improvements without changing the machine's function. The results of the DFMA analysis on the Bananas Getuk Mixer and Molding Machine resulted in a DFA Index value of 5.0 and design improvements that included the frame, mixing container, mixer, coaster, hopper, extruder, and bulkhead to increase the efficiency value of the machine.

The aims of this research is to provide optimum setting laminate oxide layer on the surface of Aluminum alloy sheet 5052-H32, also to analyze the microstructure and mechanical properties of deposited coatings as well as to compare the performance of anodization and plasma electrolytic oxidation coating in Aluminum alloy 5052-H32 sheet. Factorial L 2x3 was applied as design experiment. Which is current parameter had 2 levels; 200 and 250 minutes. Parameter Coating duration had 3 levels 15, 20, 30 minutes. The oxide layer coating is seen by conducting surface characterization. The improvement of surface hardness by micro-hardness test from 35.3 VHN to 65.8 VHN for anodizing coating, and plasma electrolytic oxidation coating is in the average of 67.9 VHN. The mechanical properties for surface hardness and adhesion strength of aluminum oxide coated of Aluminum alloy sheet 5052-H32 improved.

Abstract

The roller conveyor bearing housing is one of the injection molded products from a plastic manufacturing company in Sidoarjo. During the production process, there is an issue concerning the mismatch of the bearing housing diameter with the specified tolerance limits, which also slows down the production process. This study aims to find the optimal process parameter combination on the injection molding machine used for producing roller conveyor bearing housings. The response variable observed is the bearing housing diameter. The material used is polypropylene. The varied parameters include injection pressure, injection time, and cooling time. Data analysis utilizes the response surface method with a Box-Behnken experimental design comprising 15 experiments and 3 replications. From the experimental results, the optimal combination for both the housing diameter and cycle time responses includes an injection pressure of 60 bar, injection time of 6 seconds, and cooling time of 30 seconds. Injection pressure contributes 8.4%, injection time contributes 38.43%, and cooling time contributes 14.85% to the overall response

Abstract

Mojotamping Village is the center of the brick industry in East Java. In this village, almost 90% of the residents work as red brick makers on a home industry scale. However, the manufacturing process still uses less efficient methods. Based on these problems, a design for a clay smoothing machine and MRH red brick press specifically for home industries was created. The method used is the Ulrich method by creating 3 different design concepts by considering the specified criteria. Machine design begins with calculating machine component elements from the selected design concept as a reference in determining the size and material of the components for the clay smoothing machine and MRH red brick press machine specifically for the home industry, then designing what manufacturing processes are needed in making the clay smoothing and printing machine MRH red brick press specifically for home industries. This machine has a printing capacity of 300 bricks per hour, so if the operator runs this machine for 8 hours per day this machine can produce 2500 bricks per day. This machine is designed to use a 3 HP engine which is considered to have good fuel efficiency so it can reduce production costs when compared to existing products.

Abstract

A ship tank’s ventilation pipes protector, called PS60, is produced by an investment casting process using CF8M material. Shorter time production for PS60 products, occurred due to the rise of PS60 demand, resulting non class casting product quality. Reported that 15% of PS60 defective products were shown from each production group. Porosity defects are the most common defects found. Recalculating riser’s, runners’s, and ingates’s dimensions, then remodeling designs a mold gating system done in order to reduce the percentage of defective products and increase production capacity. Remodeling gating system and casting simulation done by ProCast 2018 software using New Advanced Porocity Module (NAPM). The casting simulation output was porosity defects location and percentage, which were further analyzed. The product produced using a mold Gating system with a new layout, had 314.73 cm3 of empty part in the mold cavity which was identified as a porosity defect which was 4.58% of the total volume of the cast product. The total value of the porosity after remodeling decreases by 2.39% from the existing product. 93.3% of the cavity inside the product is categorized as macroscopic porosity defects that are centralized in the riser and pouring basin areas, where in the casting product finishing process, these areas will be removed. Modification of the Gating System in PS60 mold escalates twice of PS60 capacity production than the origin.

Abstract

At the shipyard, the sandblasting process is routinely carried out to clean material surfaces from rust and other contaminants. This process produces waste in the form of used sand mixed with metal fragments and other debris, requiring separation before the waste can be reused as a concrete mixture. Currently, the separation process is still performed manually, which is considered inefficient due to the large volume of waste, averaging 42 tons per day. To address this issue, the author designed a sandblasting waste sieving machine to make the separation process more automatic and effective. The structural design and strength analysis were carried out using Autodesk Fusion 360 software. The simulation results of the selected design concept showed a minimum safety factor of 6.51, a maximum von Mises stress of 38.134 MPa on the main frame, and a maximum displacement of 0.186 mm on the sieve holder. The design has an estimated total manufacturing cost of Rp4.244.000,-.
