  Sheet metal is one of the most flexible materials for building a wide variety of products, such as enclosures, cabinets, housings, brackets, and assemblies. It can be made out of durable materials, like steel and aluminum, and easily customized according to the unique requirements of your project. It can be used for making prototypes, too. You just have to choose the right sheet metal prototyping service.   When you look up manufacturers who can make your sheet metal prototype, you are likely to notice many different companies locally and abroad. How do you know which one to pick? Here are some tips to help you make an informed choice:   Mind the experience   It’s important for the service provider to be experienced in sheet metal prototyping. So, find out how long they have been offering it and make sure that they have a proven outstanding track record of delivering the service cost-effectively and reliably. You might want to consider reading customer testimonials for so

If you want a low-cost alternative to common rapid prototyping and low volume manufacturing methods, you might want to consider vacuum casting. The process will cast urethane parts to create rubber-like and plastic parts. Also known as urethane casting or urethane melding, it is used in many applications and industries looking to manufacture production quality custom plastic parts without the lead time or cost associated with traditional production tooling.   Reputable rapid prototype manufacturing companies can cast parts in any size, so you can rely on them for building anything from headphones to lengthy car bumpers. Many different materials are available and can be used for your specific projects!   A speedy and efficient process   Three stages are followed to cast urethane parts . First, the master model is 3D printed via SLS or SLA, or CNC machined. Next, the liquid silicone is poured around the custom master model and cured. After dying, the master is cut from the mo

  Product development is a meticulous process that can involve a lot of trial and error. That’s because product developers, engineers, and designers have to make sure that the end result will be flawless, free of defects, and functioning as intended. To ensure high-quality results, they rely on a CNC machining prototype process to build scale models or functional prototypes of what they are making. This way, they are able to properly test, analyse the design, and refine the performance of the product before it goes into final production!   Besides that, there are other advantages that CNC machining can bring to the development of products. Here are some of them:   Fast and repeatable   The process of programming, materials set-up, and actual production is quicker when you want to build a CNC rapid prototype. Just be sure to have a good CAD file, so it can instantly be transformed into digital cutting files. CNC machining also creates the exact parts that you need and they w

As the world economy constantly grows and changes, more industries are being born. This results in more products being conceptualized and created, as many different companies continue to be innovative. As a result, market competition has toughened in an effort to meet the specific need of customers or create a new demand for one-of-a-kind products. To keep up with the competition, product designers and manufacturers must consider fast, efficient, and cost-effective manufacturing solutions, like prototype machining!   If you are making or designing a new product yourself, you will want to look into rapid and reliable modern manufacturing methods like prototype injection molding and make it a part of your industrial planning. That way, you can effectively prepare for end-use manufacturing or production of the product. With a prototype, you can have a tangible aesthetic or functional model of your idea or design, and it will enable you to effectively analyze and assess your product.

Stereolithography (SLA) is among the oldest 3D printing technologies. Despite that, it’s still widely used for its versatility. With the right SLA rapid prototyping service, you could have rapid prototypes and aesthetic models built quickly and cost-effectively out of a photocurable resin, with superb accuracy to CAD and a nice surface finish. Some companies can even provide SLA 3D printing for low volume production, and the results will be highly accurate to your design, with precise details and resolution !   But how do you find the right service provider in the US? Here are a few tips:   Find reliable and established companies   Look up rapid prototype manufacturing companies in the USA and narrow down the results to those with at least a decade’s worth of proven experience and reliability in providing SLA 3D printing services. You might want to consider looking abroad, too, so you can cut costs. Try China where SLA rapid prototyping services are likely to be more afford

There are many ways to build a prototype these days, but not all of them may be economical for you. If you need production-like parts for low volume production or prototyping with a low upfront investment, you might want to consider vacuum casting in China. The process is also known as urethane casting, and it will deliver production-quality parts without the usual lead times and costs associated with production tooling. With the right service provider, any part regardless of size can be created. That also makes the process versatile for creating many different types of products, from car bumpers to headphones.   Know how it works   Reputable rapid prototyping and manufacturing specialists offer a wide range of materials that can be used for vacuum casting in China. No matter your project, urethane casting follows three stages:   Stage 1: Master model – This is either SLA or SLS 3D printed or CNC machined Stage 2: Silicone tool – At this stage, liquid silicone is poured a
