Project for Innovative Marine Propulsion Systems Manufacturing

Meta Description

This project is dedicated to manufacturing marine propulsion systems and components for KAHE E-NAUTIC SOLUTION.

At the heart of our production process lies the integration of avant-garde technologies, notably vacuum casting and 3D printing techniques such as Selective Laser Sintering (SLS) and Stereolithography (SLA). These methods, combined with a meticulous selection of materials including Polyurethane (PU) shore, Epoxy resin, and Polyamide 12 (PA12), epitomize our commitment to delivering marine propulsion systems of the highest quality and durability.

Our manufacturing journey doesn’t conclude with the production phase; it extends into the realm of refinement and aesthetics. The finishing touches on our marine propulsion systems encompass mass tinting, precision painting, and the application of silk printing and expert stickering. These processes not only enhance the performance of our products but also ensure a polished and visually appealing end result.

In a testament to our efficiency and dedication, the entire project is scheduled for completion within an impressive timeframe of just 8 days. Our commitment is not just to deliver top-notch products, but to deliver it with a sense of urgency and precision.

Challenge and Solution

 Our project delves into the intricacies of the following challenges and explores effective solutions to achieve flawlessly assembled prototypes.

1. Precision Assembly of Diverse Prototyped Parts

This initiative takes on the intricate challenge of flawlessly assembling components manufactured through various prototyping methods.

Achieving accurate assembly of 3D printed and vacuum-casted parts demands strict adherence to 2D plans. Ensuring dimensions and quality necessitates the expertise of highly skilled technicians experienced in executing these intricate operations.

While 3D printed parts are valued for their versatility, they may sometimes lack the precision required for seamless assembly according to design specifications. To overcome this challenge, our engineers optimized the fit gaps between parts based on real-world conditions, making manual adjustments as needed. This process involved a thorough analysis of Design for Manufacturing (DFM) principles to fine-tune assembly clearances.

Additionally, achieving precise assembly of 3D printed and vacuum-casted parts requires strict adherence to 2D plans, akin to the processes used in over-molding. To maintain dimensions and quality, we rely on highly skilled technicians with extensive experience in executing these intricate operations.

Addressing physical deformation of manufactured parts during assembly poses a challenge. To mitigate and reduce this deformation, we employ various post-processing techniques, including manual adjustments, the use of jigs and fixtures, and anti-deformation methods such as baking in an oven. In some cases, secondary processing is also utilized to effectively address these issues.

2. Accurate Placement of Silk Printed Logos

Achieving precise placement of silk printed logos necessitates the use of specialized tools and jigs, emphasizing the meticulous attention to detail integral to our assembly processes.
