  Injection molding can crank out identical plastic parts quickly and efficiently. This high-volume and repeatable process saves time and money for complex parts, but choosing the right manufacturer is key. Not all China-based injection mold service providers offer the same quality, so research is crucial.   Here at HLH Prototypes, we work with many companies looking to require affordable and fast injection molding services for low-volume production of up to 100,000 parts. Moreover, we make sure their parts are identical to their final versions using production-grade materials. These capabilities put us among the best prototype manufacturing partners for designers and engineers in various industries, such as automotive, aerospace, telecommunications, and medical.   In this blog, we’ll share other factors that make us the best company to engage for your China injection mold project.   End-use prototype manufacturing   Our injection molding capabilities allow us to produ

  China has proven itself the powerhouse when it comes to affordable CNC machining and prototype manufacturing. Companies from different countries around the world turn to China-based manufacturers to save time and money when bringing their designs to life for testing and verification — and perhaps you should, too. With low material, labor, and infrastructure costs, CNC machining and prototype providers can help you save anywhere from 20% to 30% compared to in-house production or outsourcing to Western suppliers.   To ensure cost-effective CNC services, take the time to verify the experience, qualifications, manufacturing standards, and reliability of potential service providers. Additionally, find out how they can support your design and manufacturing process before, during, and after working with you.   This guide hopes to cover everything you need to know to ensure cost-effective CNC machining and prototype services in China.   Capabilities   Reputable CNC serv

  If injection molding is too time-consuming and costly for your project, explore the alternative: vacuum casting. This process can produce high-quality cast urethane parts with a good surface finish at a reasonable cost. At HLH Prototypes, we recommend this service to clients looking to save time and money when making functional and aesthetically pleasing self-colored parts with a repeatable process. Although similar to injection molding, its tooling costs are significantly lower, making it a go-to option for bridge production, prototyping, and end-use production of less than 100,000 parts.   Here at HLH Prototypes, we can produce cast urethane parts of any size, from small items like headphones to large objects like car bumpers. Our wide range of materials and capabilities allow us to deliver high-quality and reliable parts for pre-production testing.   What’s involved in vacuum casting?   We follow the standard vacuum casting process in three stages: ·      Creating

While often considered optional, the right colorants can significantly impact a plastic part's properties and aesthetics. At HLH Prototypes, we share your vision for high-quality, functional, and visually appealing parts made with custom China injection molds . That's why our team collaborates closely with you to meticulously choose the ideal materials, including colorants, for your project's success. Color selection depends on many factors, such as your choice of plastic and the part’s final application. We also consider environmental factors, budget, and durability before recommending appropriate colorants. In this blog, we’ll explain how colorants can affect your plastic part. Understanding the effect of colorants on plastics Adding colorants to a plastic part can affect its properties, so we carefully consider the compatibility between the chemistry of the colorant and that of the polymer. In addition, the effects of a colorant on the polymer’s properties depend o

  Product innovation calls for a transformative approach that involves a low investment without compromising long-term ROI. This is where rapid prototyping comes in. Here at HLH Prototypes, we apply a dynamic approach that delivers a streamlined solution for building a custom  China-based rapid prototype  that helps product engineers and designers test and verify their designs and implement continuous iterations. Rapid prototyping means creating a functional or aesthetic tangible model of an envisioned design or idea. The iterative process allows designers and engineers to explore their part’s features and discover various concepts quickly and cost-effectively. At HLH Prototypes, we help these professionals invest in high-quality and accurate resources to support their experimentation, refinement, and learning. In this blog, we share more details on how rapid prototyping can accelerate innovation for your business. Invest small and get the best returns. One of the perks of choo

Urethane casting can be a reliable and cost-effective manufacturing method for low-volume identical prototypes or end-use parts. Also known as vacuum casting, it involves a custom silicone mold and a urethane casting resin that will be cured and cooled to produce the component. This process makes  cast urethane parts  faster and more affordable.           Although this method is widely used, many product designers and manufacturers are still unaware of how beneficial it can be for their projects. Some manufacturers only use it for bridge tooling to make prototypes before using injection molding for end-use production, overlooking the vast benefits and uses of urethane casting. This blog hopes to explain the advantages and applications of  cast urethane parts . ·          Enhanced design flexibility - Urethane casting allows product designers to be more flexible as it offers access to various materials in different durometers and colors. Moreover, it’s easier to introduce design
