CUSTOMER - ARCESSO DYNAMICS

COMPANY INTRODUCTION

Arcesso Dynamics is a medium-sized company (25 employees) with more than 10 years of history, committed to providing short and medium runs of polyurethane parts with high-quality finishing (painted parts, glossy finishes, etc.), mainly for general industries such as furniture, medical equipment, electronical devices, and more.

Arcesso Dynamics has a clear focus on innovation, continuously developing improved polyurethane formulations with unique properties, as well as processes.

As the manufacturing of big parts is the optimal work point for RIM technology, Arcesso Dynamics mainly deals with this type of design; they see a lack of competitiveness of the technology against Injection Molding when it comes to medium and occasionally short series of small- or medium-sized parts.

One of their main concerns in their daily business is that many times they are forced to reject incoming projects consisting of little parts of short batches because of the high costs of the RIM molds.

Finding a way to address these series of little parts with a lower initial but not less important—advantage of using HP MJF RIM molds is time to capital expenditure would increase their market significantly. A second— months of labor. Being able to deliver polyurethane final parts in days market. Manufacturing of a machined mold typically takes weeks to increases chances of deal-closing exponentially.

APPLICATION VERTICAL: Industrial services

APPLICATION SUB-VERTICAL: Molds

The goal is to be able to replace current silicon molds with an HP MJF mold and to avoid the need for periodic mold replacements

This mold has a variety of detailed features (e.g., cuts, holes, engravings, details) and has performed better than silicon molds in terms of dimensional stability. (A mold is not a copy of a master part but a printed part itself.) This ensures final parts with straight edges, dimensions, and warpages.

Mold polishing requires some cautious handwork; mold coating will be evaluated in future investigations

RIM technology is widely used in the manufacturing of low-volume big plastic parts (machinery covers, medical device covers, etc.) using polyurethane material in diverse formulations and densities

Polyurethane-curing chemical reactions that happen inside an RIM mold normally take place at low and low-temperature working parameters make HP Multi Jet Fusion materials very suitable temperatures and pressures, compared with the conditions of plastic Injection Molding. These lowpressure for RIM mold manufacturing.

Currently, RIM technology is the optimal technology for producing short runs of big plastic parts, such within other families of parts. This competitiveness is lost against plastic Injection Molding when it as machinery equipment covers or medical device housings, but also automotive foamed components mold prices.comes to small- or even medium-sized parts due to individual part manufacturing costs at similar

WHY HP MJF

By using HP Multi Jet Fusion molds, fabrication fixed costs will be reduced to a fraction of the original values, allowing the technology to address a much wider market of small- and medium-sized plastic parts.

  • Chemical compatibility: The chemistry behind polyurethane is complex, and many materials are not compatible with the technology, which affects the curing reaction process (e.g., silicones, moisture in materials, etc.). HP 3D HR PA 12 has proven to be compatible with polyurethane molding.
  • Cost: HP MJF will allow for the creation of molds from a CAD-designed file, which eliminates the intermediate steps in the process compared with CNC (CAM, pre-setting machining tools, etc.). The price of a medium-size part mold will be reduced by 10% to 20%.
  • Weight: Usually, 3D printing materials are lighter than aluminum or steel. Furthermore, 3D printing allows for the creation of high-rigidity, lightweight lattice structures that reduce mold mass and maintain mechanical properties.
  • Freedom of design: Mold tempering and heat removal homogeneity are key in reaction Injection Molding. HP MJF allows for the creation of complex, close-to-surface cooling conduits, increasing process performance.
  • Mold texturizing: Using HP MJF technology will allow textures, such as wood and leather, to be directly printed into the mold, preventing high costs and timings on manual mold texturizing processes.
