HLH Proto's Guide to High-Quality Cast Urethane Parts

Need to produce a small batch of complex prototypes? Vacuum casting could be the ideal manufacturing method for you. Also known as urethane casting, the process eliminates the gap between end-use production and rapid prototyping. Vacuum cast parts are precise, high-quality, and consistent, allowing for swift product development. Moreover, it empowers your design and engineering team to maintain the highest production standards while bringing concepts to life at a reasonable cost.

 

Vacuum casting is among our specialties here at HLH Proto, and in this blog, we will share how our service can deliver cast urethane parts quickly and cost-effectively.

 

Faster than injection molding

 

If you only need a small quantity of high-quality rubber-like or plastic parts, we recommend vacuum casting over injection molding. It’s faster and more cost-effective because it doesn’t involve production tooling. At HLH, we can produce vacuum-cast parts of any size, from car bumpers to earphones. Despite the low-cost tooling, urethane casting can produce thousands to millions of similar components.

 

Applications of cast urethane parts

 

Vacuum casting is ideal for prototyping low-volume identical parts. The process can generate high-quality rubber or plastic parts as rapid iterations or samples for market testing. Additionally, it’s cost-effective for low-volume end-use production. At HLH, you only require a low upfront investment for our service, and we will deliver self-colored, production-like parts to support your product development or final production requirements.

 

How vacuum casting works

 

Our process starts with a CNC-machined or 3D-printed master model of your part. If we use 3D printing, we prefer stereolithography (SLA) technology. Once the master model is ready, we pour liquid silicone into it and wait for it to cure. When it’s dry, we cut the master from the mold, leaving the cavity. Then, we are ready to vacuum cast parts by pouring resin into the cavity. This should result in production-grade parts to support real-world testing.

 

Meeting industry standards

 

Here at HLH, we offer IATF 16949, ISO 14001, and ISO 9001 certifications to ensure high-quality cast urethane parts that meet industry standards. Our process guarantees detailed, uniform parts with excellent dimensional accuracy and surface finish.

Art of Die-Casting: What Sets It Apart

If you require metal parts or prototypes in larger quantities, there are affordable manufacturing options that can decrease your production time and provide precise outcomes. Die-casting services are a great choice, particularly when you need parts manufactured from magnesium, zinc, or aluminum. You may be wondering: What distinguishes it from other manufacturing services like direct metal laser sintering (DMLS), injection molding, or CNC machining? Continue reading to learn about the process and its advantages.     How die casting works   Die casting follows a similar process to injection molding, but this time, for metals. That means a custom mold will be made based on your part’s design, and it will be installed on the die-casting press. When it’s ready, molten material will be injected at high pressure into the tool cavity. The finished parts can be further processed and finished by anodizing, powder coating, and other ways to meet your requirements.     Different t

What is SLS 3D printing?

Image
  SLS stands for Selective Laser Sintering, which is a 3D printing method where a polymer or thermoplastic powder is sintered by pointing a laser that transforms the powder into a solid plastic piece. This process is part of the group of Powder Bed Fusion technologies, and it achieves the fusion of the material by layers that represent cross sections of the model built in the CAD/CAM software. Although the explanation above seems to be describing a newly developed technology, the truth is that SLS 3D printing is one of the oldest additive manufacturing methods, first developed in the 80s by doctors Carl Deckard and Joe Beaman at the University of Texas at Austin. As with other 3D printing processes, it all begins with a 3D CAD model that is processed by the software of the printer to generate the layers that will be printed. After that, the SLS 3D printing process takes the following steps: 1.The platform where the piece is printed is located inside a chamber known as the powder bin or

Benefits of 3D Metal Prototyping for Manufacturing

  Metal prototyping lets you test the function, durability, look and feel of a designed part prior to sending it out for manufacturing. The test run eliminates the risk from the investment and enhances customer satisfaction. There are numerous ways to prototype any metal component, and they all have their own positives. 3D metal printing During the process, a laser selectively attaches together metal elements on the print bed whilst the machine distributes metallic powder layers evenly.   Faster production times Components created by conventional manufacturing processes such as forging and casting might take anywhere from weeks to months. With metal prototyping, components can be manufactured in just a few days' time, thereby facilitating efficient design alteration and faster time to market.   Cost-effectiveness 3d metal prototyping saves time and money as it is less reliant on secondary processing. 3D printers need less attention during the production phase, so ope
