Haizol for Injection Molding Quotes Online

Haizol is a verified custom-manufacturing marketplace in China that provides multiple quotes from pre-vetted suppliers with transparent direct-factory pricing and guided quoting support. The platform operates on a direct-to-factory sourcing model, meaning companies work directly with manufacturers rather than intermediaries.

Launched in 2015, Haizol connects international buyers with verified manufacturers across China, including factories providing custom plastic molding services. It is used by procurement managers, engineers, and SMEs to source accurate quotes for molded components and tooling.

Haizol’s supplier network is composed of pre-vetted injection molding Chinese factories, with verification covering credentials, production capabilities, and past manufacturing experience. Each injection molding project can be supported by a dedicated account manager who assists with clarifying drawings, communicating technical requirements to factories, and coordinating production.

Factories on Haizol support a range of mold types, including single-cavity, multi-cavity, family molds, insert molds, overmold/2K molds, hot-runner molds, and prototype (aluminium) molds. Typical tolerances are ±0.05–0.10 mm for most commercial molders, with tighter tolerances available for precision parts. Mold fabrication lead times ranging from 3-4 weeks for simple aluminium tools to 6–10 weeks for complex steel molds.

Production volumes for injection molding ranges from Haizol suppliers run from a few hundred prototypes to 5,000–50,000 units and high-volume runs into the millions, depending on the supplier’s machine fleet and specialization.

All supplier profiles viewable, the factory size, machine tonnage ranges, mold-making capabilities, monthly capacity, workforce size, certifications (ISO 9001, IATF 16949, etc.), and export experience. This visibility helps procurement and engineering teams to evaluate technical fit and reduce risk when selecting a supplier.

What Customers Say About Haizol: Benefits and Limitations

“The entire process was very simple to carry out, from sending the manufacturing drawings, receiving many offers and finally selecting the right supplier. The system works perfectly and is friendly. In addition, Meriam Sembrino is an excellent account manager, very kind and eager to help make everything work perfectly.”

Francisco Zapata (Chile) Trustpilot Review.

“The service appears a convenient 'short cut' way to obtain multiple quotes for manufacturing and may suit other businesses more than mine. There is very little to distinguish between suppliers in order to allow a clear choice or to give confidence.”

David R (GB) TrustPilot Review.

 

Xometry for Injection Molding Quotes Online

Xometry is a well-established U.S on-demand manufacturing marketplace is known for its instant-quoting engine, allowing engineers to upload CAD files and receive pricing, DFM guidance, and lead-time estimates for injection molding projects within minutes.

The company provides a turnkey operation with access to around 4,500 vetted manufacturing partners across North America, Europe, and Asia. The platform itself manages the tooling, production, inspection, logistics, and shipping processes for customers, and the actual pricing facing the customer will be determined by Xometry rather than the partnering factory.

The platform is favoured by teams seeking tooling and plastic injection molding from local or near-shore molders capable of producing small- to mid-volume production runs.

Xometry supports a range of injection molding tooling options, including aluminium prototype molds, single- and multi-cavity steel molds, family molds, insert/overmolding (2K), hot-runner systems, and production-grade hardened steel tools. Typical tolerances quoted on the platform fall around ±0.127 mm for commercial molded parts.

Standard mold fabrication lead times quoted through Xometry range from 2–4 weeks for simple aluminium prototype molds to 6–9 weeks for more complex or hardened-steel production tools. Production batches typically range from 100-piece prototype runs to 5,000–100,000+ unit series, production depending on mold type, press tonnage, and partner capabilities.

As one of the leading online injection molding platforms, Xometry offers a robust quality assurance program, including global QA labs that can inspect final molded parts against specifications before shipping. An added verification layer not provided by most other platforms. Dedicated account managers are available for high-value or enterprise accounts.

What Customers Say About Xometry: Benefits and Limitations

“When I’m working on early prototypes, I really value how easy it is to get helpful engineering feedback and move an idea forward. The whole process feels straightforward, and I genuinely feel supported from start to finish. Xometry has become a go-to resource for bringing my projects to life.”

Valeriy Novytskyy (US) TrustPilot Review.

“Xometry works great when using the instant quote…However, anything that required a manual quote was a very different story. While I was back and forth with emails and calls, often several times a week regarding manual quoting…I ultimately never received any of the three manual quotes I requested.”

Michael (US) TrustPilot Review.

Alibaba RFQ for Injection Molding Quotes Online

Alibaba’s ecommerce marketplace of 200,000+ suppliers also offers an RFQ service for custom injection molding and other machined parts. Unsurprisingly, for the world’s largest B2B trading platform, it remains one of the most accessible places to obtain injection-molding quotes online.

Engineers and procurement teams sourcing molded components, tooling, and related OEM services can submit drawings, specify materials (ABS, PP, PA, PC, TPU, etc.), define tolerances, and set quantity requirements in their RFQs.

Injection molding suppliers on Alibaba RFQ commonly offer single- and multi-cavity molds, aluminium prototype molds, family molds, insert molds, overmold/2K tooling, and cold- or hot-runner systems. Achievable tolerances vary widely across suppliers.

Once an RFQ is submitted, buyers often receive initial responses within six hours, after which they can communicate directly with potential factories. Typical mold fabrication lead times range from 3–4 weeks for simple prototype molds to 6–10+ weeks for production-grade steel molds.

Production volumes can span from a dozen prototype shots to tens or hundreds of thousands of units. This varies greatly as the platform’s open, general-purpose marketplace offers broad supplier diversity.

Procurement teams must be specific when outlining requirements, as many suppliers specialize in consumer goods rather than custom precision tooling, and trading companies rather than factories may respond to RFQs. All suppliers and quotes should be independently verified, as hands-on support is minimal. Alibaba’s Trade Assurance can help protect payments but does not replace thorough supplier vetting.

What Customers Say About Alibaba: Benefits and Limitations

“This sample is fantastic. The product quality is great, and it arrived faster than expected. We also had a great experience with Angela LV. She was very attentive, always willing to help, and quick to answer all of our questions. Excellent product and service all around!”

Diego Brito (Panama) Trustpilot Review.

“I bought some machinery for 13.5k and did not get a receipt of payment, so if you decide to ignore people on Trustpilot to avoid the site, it is up to you but if you experience some misdoing, you have been warned. I have no idea where my money has gone and they are in no rush to solve the issue…”

Sean Bowman (GB) TrustPilot Review.

 

Made-in-China for Injection Molding Quotes Online

Made-in-China is one of the largest China-focused sourcing marketplaces, with roughly two million export-oriented vendors, making it a major destination for obtaining injection molding quotes online.

Its scale means buyers can find suppliers capable of producing everything from prototype tooling to large-volume molded parts. But this also places more responsibility on internal sourcing and procurement teams to verify capabilities, manage quality, and ensure they are working with a true injection mold maker rather than general consumer-goods factories.

Many suppliers on Made-in-China can produce standard tooling such as single- and multi-cavity molds, family molds, aluminium prototype molds, insert molds, 2K/overmolding tools, and hot-runner systems.

Mold fabrication lead times range from 3–4 weeks for simple prototype tooling to 6–10+ weeks for hardened-steel production molds. Many suppliers are well-established exporters to the West.

Production quantities can vary greatly—from small prototype runs of 50–200 shots to mid-volume batches (5,000–50,000 units) and high-volume orders in the hundreds of thousands or millions, depending on factory size and tooling approach.

Like Haizol, Made-in-China is entirely China-centred and benefits from the country’s cost-efficient production, manufacturing scale, and fast turnaround times from its injection molding suppliers. However, due diligence reviewing certifications, inspecting sample work, checking mold design capabilities, and confirming direct factory ownership, is essential.

 

What Customers Say About Made-in-China: Benefits and Limitations

“I've had very good communication with the seller. The parts are very good. I'm very satisfied. I strongly recommend them.”

Anonymous (Romania) TrustPilot Review.

“Definitely better off spending a little bit more and getting a product that’s been manufactured in the UK we have bought many products made in China that have given us very poor results.”

Graham (UK) TrustPilot Review.

 

How to Choose the Right Injection Molding Platform

When you start to compare injection molding sourcing platforms, it’s important to look far beyond the numbers in the quotes you receive. When Western customers have faced problems, it’s often because they didn’t thoroughly assess the platform they used or the suppliers they selected.

The best injection molding platform for your business depends largely on how developed your procurement and supplier-management processes are. Particularly when it comes to evaluating platforms and overseeing injection molding partners. Companies with less sourcing experience may need straightforward, guided solutions, while more advanced teams require greater visibility, flexibility, and strategic control.

The table below outlines the main considerations when choosing the most suitable injection molding platform based on the sourcing “maturity” of your procurement team:

 

Frequently Asked Questions on Injection Molding Sourcing Platforms

How Do I Know if the Supplier I Work With Has Been Verified by the Platform?

The visibility level of verified injection molding suppliers depends on the platform. Haizol, Alibaba, and Made-in-China make supplier verification visible on profiles, while Xometry verifies suppliers internally without exposing individual factory pages to procurement professionals.

What Are the Risks of Using Open Marketplaces?

Some of the risks of using open marketplaces are receiving quotations from unvetted and unreliable suppliers, platform workflow issues compromising the final order, suppliers misunderstanding drawings, IP risks, and the risk of sacrificing quality for lower prices. 

How Fast Is a Quote From These Platforms?

Single quotes with Xometry are instant, while Alibaba RFQ can provide multiple quotes within six hours (but may take longer). Haizol usually offers multiple quotes within 24 hours, and Made-in-China provides multiple quotes usually within 24–48 hours of the RFQ.

Do Online CNC Platforms Support Custom Materials or Tight Tolerances?

Most online injection molding platforms do support custom materials and tight tolerances, but the level of support varies greatly between platforms.

What Happens if Something Goes Wrong With My Injection-Molding Part or Delivery?

That depends on where you bought it from. With Haizol, a dedicated account manager can take the issue up with the supplier. Xometry has a Return Merchandise Authorization policy for quality issues. Orders placed with Alibaba RFQs Trade Assurance are protected under the platform’s dispute resolution system, and Made-in-China offers a 30-day refund for delivery or product issues.

Conclusion: Choose an Injection Molding Platform Based on Your Project Needs

No single injection molding platform fits every sourcing requirement. The right choice depends on factors such as part complexity, required turnaround speed, geography, supplier transparency, pricing structure, and the level of support your team needs.

Haizol is best for verified China-based custom injection molding with direct-factory pricing. Xometry is suited for fast-turnaround injection molding in the US and EU. Alibaba RFQ works well for broad supplier discovery, while Made-in-China is a strong option for high-volume sourcing.

The four platforms covered all offer benefits for getting CNC quotes online in 2026 but each offers different pros and cons when it comes to the key considerations, such as supplier capabilities, quality assurance, cost efficiency, quote speed, and support models, so the best fit depends on your project’s priorities.
