Our digital factories create prototypes and low-volume parts fast, while our manufacturing network, offers advanced capabilities and volume pricing.

No one ever said that designing and manufacturing molded parts was easy. Our goal is to get you through it quickly and with quality parts. A good starting point is our Design for Moldability Toolkit.

Injection molding is widely used for plastic part production in medical, consumer, and automotive industries. Typical parts include:

Aluminum moldsStandard lead times as fast as 7 daysTolerances of +/-0.003 in. plus resin tolerance (in./in.)Set-up fees apply to each run Consultative Design Services (CDS)Finishing OptionsNo minimum order quantities (MOQ)Quick-turn shipping in as fast as 1 day

Because of the initial capital investment in tooling, injection molding makes sense for higher volumes of parts. Our mold cost starts at $1,495 and will vary depending on part geometry and complexity. Other factors that will impact injection molding cost are lead times and material.

Unmatched Lead TimesReduce your product development cycle by weeks—sometimes months—and bridge to production with injection-molded parts within days. Some injection molding orders can ship in as fast as 1 day.

Make the move from prototyping to on-demand manufacturing for affordable, high-quality molded parts within days. Better yet, your prototyping tool is free once you shift to an on-demand manufacturing tool. Working with a single supplier that provides free design consultation services also massively speeds up the manufacturing process, allowing for greater supply chain flexibility, more consistent parts, and making qualification a breeze.

Design for Manufacturing FeedbackEvery quote includes real-time pricing and design analysis. We evaluate your 3D CAD and help identify any features that may pose challenges during the molding process such as difficult to machine undercuts and insufficient draft.

We do quoting a little differently. When you request an injection molding quote, you'll not only receive accurate pricing, but also a manufacturing analysis—within just a few hours. Our online quoting platform also provides you with gate and ejector pin layouts and a price curve tool to help select the best tooling option for your project.

This complete reference guide walks you through everything from quoting, design analysis, and shipment to best practices that ensure your model is optimized for molding.

No Minimum Order Quantities (MOQs)Procuring parts on demand, without MOQs, helps you manage market or demand volatility and provides a cost-effective source for bridge production, line-down emergencies, end-of-life production, or product customization.

Our helpful design aid demonstrates part features that are too thin or too thick, bad bosses, right and wrong ribs, and other considerations to be mindful of while designing parts for injection molding.

Overmolding and insert molding are two-part injection molding processes where one material is overlaid onto a second substrate part or metal insert to create a single component.

Tough Black (Loctite Henkel 3843) and Ceramic-Filled (BASF 3280) are two new advanced photopolymer materials now available for 3D printing.

Plastic injection molding is a manufacturing process where resin in a barrel is heated to a molten state, then shot into a mold to form a final production-grade thermoplastic part.

Yes, we offer a production tooling option called on-demand manufacturing. This tooling option provides several benefits: lower piece part price, multi-cavity capabilities, guaranteed tooling for the life of the project (we will cut a new tool if it wears out), and first article inspections.

Injection Molding ExpertiseWe'll work with you throughout the course of your project to help you quickly move from prototyping to production, including finishing options and inspection reporting.

Injection molding is plastic manufacturing process that can produce high quality parts at scale. It's typically used for low- to high-volume production but our aluminum tooling can also make prototyping runs economical.

We have wide selection of more than 100 thermoplastic and thermoset materials. And if you're looking for alternative material options, check out our guide to resin substitutes for ABS, PC, PP, and other commonly molded plastics.

Liquid silicone rubber molding is a thermoset process that mixes a two-component compound together, which is then heat cured in the mold with a platinum catalyst to produce a final part.

In most cases, we can maintain a machining tolerance of +/- 0.003 in. (0.08mm) with an included resin tolerance that can be greater than but no less than +/- 0.002 in./in. (0.002mm/mm).

Their sophisticated product portfolio of Secure Base URL">injection moulding machine construction covers the entire spectrum of the plastics processing industry and meets the most diverse customer demands for the manufacture of mass and high-precision plastic products.

We have two unique offers to meet your needs wherever you are in the product lifecycle. Our prototype injection molding process helps you cut product development cycles by weeks—sometimes months—and bridge to production with injection-molded parts within days. Our On-demand Manufacturing process is designed to meet your production needs, and helps you qualify parts quickly to seamlessly transition into production with scientific molding, in-process CMM inspections with GD&T, and a full suite of secondary operations to make sure that your parts show up and perform as expected.

Haitian has a solid foundation to take care of what customers really need. They have been sustainably developing their service team and service skills from learning from the past and accumulation of practical experience. They have a well-trained after-sales service team with excellent technical qualification and profound practical experience.

Get machined parts anodized and chromate plated with our quick-turn finishing option. Eligible materials include aluminum 6061/6082 and 7075.

We combine scientific (or decoupled) molding techniques, which optimize and lock in processing parameters to ensure part consistency—with extra attention paid to critical-to-quality dimensions using our proprietary automated CMM process. Plus, with every order you'll get:
