Analysis of Process Failures in Plastic Product Manufacturing Using Blow Molding Machines

Muhammad Alriz Nur Aftian — 2024-03-13

Abstract. The rapid advancement of technology, particularly in the plastics industry, is closely intertwined with the
development of machinery used in plastic production processes. Commonly used machines in plastic raw material
production include blow molding, injection molding, and extrusion. The production cycle time significantly affects
both the quality and quantity of production. While a faster production cycle may increase the quantity of output, it
does not necessarily guarantee an improvement in product quality. Hence, it is imperative for companies to identify
factors leading to production defects to plan controlled improvements. Product quality is a crucial consideration for
consumers when selecting products. PT. XYZ Pasuruan, a manufacturing company specializing in plastic packaging
processing, faces production issues involving defective products and the underlying factors causing them. This
results in time and cost losses due to the need to reproduce faulty products. Therefore, this research aims to develop
effective strategies for preventing and reducing production defects. Possible measures include improving production
processes, machinery, employee training, or changing raw material suppliers. By addressing the root causes of
these issues, the industry can enhance product quality, reduce production costs, and increase customer satisfaction..

Abstract. The welding process is widely used to join metals. However, there are still many welders who have not
mastered welding techniques that comply with the standards set by welding associations. This research was
conducted to find out how the welding process and maintenance of factory work tools works. Research begins by
identifying machine damage or factory equipment damage. Once the damage is known, repairs are then carried out
on the damaged machine. The results of research regarding welding and maintenance of factory work equipment
show that damaged factory equipment must receive regular inspection and maintenance. Factors that cause damage
to factory work equipment are human error, lack of diligent cleaning of industrial work tools, and can also be
caused by the age of industrial machines.

Corrosion Rate Analysis of Steam Boiler Superheater

Satria Agung Wibisono — 2024-03-20

Superheaters play an important role in converting saturated steam to the point of superheating. The condition of the superheater needs to be considered, if there is rust it will reduce the performance of the superheater in heating steam to the point of superheat. Rust / corrosion is the enemy of dangerous metals. Corrosion is defined as a deterioration in the quality of metals due to electrochemical reactions with their environment In corrosion events, metals undergo oxidation, while oxygen (air) undergoes reduction. The corrosion event itself is an electrochemical process, which is a process (change / chemical reaction) that involves electricity. Certain parts of the metal act as the negative pole (negative electrode, anode), while the other part acts as the positive pole (positive electrode, cathode). Electrons flow from the anode to the cathode, resulting in corrosion. By calculating the corrosion rate of superheaters with material A-213 T22 can be a consideration for using materials that are more resistant to rust or become a consideration in estimating repair time.

The method in this research uses the observation method, namely the method of collecting data by recording directly while in the field. The research results show that the use of a Yamaha F100B outboard motor as a propulsion is able to provide adequate thrust for the survey vessel, with efficient fuel consumption. In the context of survey vessels, the reliability and speed of these motors are important factors in supporting successful marine survey operations.

P-702 Centrifugal Pump Damage Analysis Insights and Implications

Keigen Abdullah Barafi — 2024-03-20

Centrifugal pumps are widely used in industries for fluid transfer, operating on the rotation of an impeller driven by a prime mover. However, sudden performance drops and operational instability pose significant challenges, impacting overall system efficiency. Predictive maintenance relies on vibration analysis to assess rotating equipment condition, with vibration patterns indicating potential issues such as cavitation and corrosion. Prolonged cavitation leads to erosion of channel wall surfaces, resulting in structural damage. This study aims to address the knowledge gap in understanding the relationship between pump vibration, cavitation, and corrosion. Through comprehensive vibration analysis and examination of pump performance, our research identifies the mechanisms driving pump degradation. The findings highlight the critical role of predictive maintenance in mitigating pump failures and optimizing system performance.

Highlights :

Vibration analysis crucial for predictive maintenance: Identifying early signs of pump deterioration.
Cavitation-induced erosion: Understanding the impact of prolonged cavitation on pump performance.
Importance of proactive maintenance: Mitigating pump failures and optimizing system efficiency.
