Send us your drawing, reference product, 3D file, or sketch. We review the design with our mold engineers and assess whether the structure is manufacturable as specified, or whether adjustments are needed for optimal injection performance. This review is provided at no charge.
Expert Tooling Management
The Mold Is Where Your Claw Clip Begins.
We manage your custom mold development from engineering to final trial. We act as your single point of accountability, seamlessly integrating precision tooling into our injection production lines.
Most manufacturers leave you to figure out the tooling risks. At Claw Clip Factory, we partner with specialized tooling facilities to cut your mold under our strict engineering guidelines. Once ready, we bring it directly to our injection floor. This means you get the best mold makers combined with our rigorous mass-production quality control — with no communication gaps.
In-House Assembly
Spring insertion done right.
Spring assembly sounds simple. In practice, consistent spring placement — at the correct tension, in the correct position — is where clip quality issues most commonly originate. Here is how we control it.
01
Tooth alignment & jaw symmetry
Claw clip teeth need to interlock cleanly when the clip closes. If the upper and lower jaw molds are not precisely matched, clips will close unevenly, look misaligned on shelf, and frustrate the end user. We review tooth structure and jaw pairing at the design stage — before any steel is cut.
02
Opening force & spring compatibility
Standard claw clip sizes cover most markets, but if your target customer has specific needs — an unusually large jumbo clip, a very specific mini size, or an intermediate format — a custom mold cuts to your exact specification with no compromise.
03
You want a buyer-exclusive design
Brands that want to prevent direct copying develop their own mold for a clip shape their competitors can’t easily source. Once your mold is on our floor, it belongs to your production relationship with us — we don’t use it for other clients.
04
Your current supplier's mold isn't performing
If you’re experiencing inconsistent clip quality from another source — surface defects, alignment issues, spring fit problems — the root cause is usually the mold. We can evaluate the issues and develop a replacement mold that solves the structural problems at the tooling level.
Step by Step
How we take your concept to a production-ready mold.
Step 1 — Reference Review
Step 2 — Feasibility Check
We evaluate critical design elements: wall thickness uniformity, gate placement options, draft angle availability, parting line location, and tooth structure integrity. If any element poses a production risk, we document it and propose a solution before proceeding.
Step 3 — Mold Quotation
We provide a full tooling quotation including mold cost, expected sample timeline, and recommended injection molding parameters for your clip design. Mold cost is a one-time investment. There are no ongoing tooling fees as long as you continue producing with us.
Step 4 — Tooling Production
Once the project is confirmed, our CNC workshop begins cutting the mold. We use hardened steel for production molds intended for long-run use. Mold construction is performed entirely in-house, with no outsourcing of critical tooling operations.
Step 5 — First Trial Shots
The completed mold runs its first trial injection. Trial shots are inspected against the design specification — dimensions, surface quality, gate witness marks, and structural integrity are all evaluated. This is the stage where most mold adjustments are identified and corrected.
Step 6 — Sample Production
After trial shot approval, we produce a sample set for your review. Samples are assembled with springs and finished to your surface specification. You receive physical samples that represent what bulk production will deliver.
Step 7 — Revision (if required)
If the sample reveals issues that need mold-level correction — shape deviation, surface imperfection, or functional problem — we modify the mold and re-sample. Revision support is included as part of the tooling project.
Step 8 — Release for Production
With sample approved, the mold is formally released for bulk production use. Production parameters are recorded and maintained as the standard for all subsequent runs using this tooling.
Before Bulk Begins
We test the mold — not just the sample.
A sample can look good while the mold has underlying issues that only appear at volume. Our trial process is designed to surface those issues before they become your problem in a bulk order.
Check 1 — Shape & dimensional accuracy: We measure critical dimensions on trial samples against the design specification.
Check 2 — Surface condition: We inspect trial shot surfaces for flow lines, sink marks, and weld lines.
Check 3 — Opening & closing performance: Assembled trial samples are tested for opening force, closing alignment, and spring function.
Check 4 — Tooth alignment & jaw closure: Upper and lower jaw components from trial shots are checked for tooth interlock accuracy.
Check 5 — Cycle stability: We run the mold through extended cycles to observe consistent output.
Tooling Standards
The equipment standard we demand.
We only partner with specialized tooling facilities equipped to meet our high standards. This ensures the mold delivered to our injection floor is ready for bulk scaling without compromise.

Single Point of Accountability
Seamless transfer from tooling to production.
When tooling and production are handled by completely different companies without a bridge, accountability gets lost. If a defect happens, the mold maker blames the injection factory, and the injection factory blames the mold.
We eliminate that risk. We manage our tooling partners strictly. Once the mold is completed, it is brought directly to our injection facility. We run all trial shots on the exact machines that will produce your bulk order. If the sample needs adjustment, we handle the coordination.
To you, the experience is seamless. You deal with one team, one timeline, and one quality standard.
Long-Term Tooling Support
Your mold. Maintained for the life of your production.
Molds wear over time — especially around high-cycle areas like gate points, parting surfaces, and cavity details. A mold that isn’t maintained loses dimensional accuracy.
For clients who continue producing with us, we maintain your tooling safely on our factory floor at no additional charge. This includes:
• Regular inspection of mold condition between production runs
• Cavity cleaning and polishing to maintain surface quality
• Safe storage in our facility for quick repeat-order deployment
“We don’t charge for mold maintenance on active production accounts. It’s part of how we run a long-term production partnership.”
Frequently Asked Questions
What is your minimum order quantity (MOQ)?
Standard MOQ starts at 1,000 units per style for existing designs. For custom mold development, the MOQ is typically 5,000 units. We’re open to discussing smaller trial orders for new clients — feel free to reach out.
How long does custom mold development take?
From CAD approval to physical sample, the process typically takes 15–21 business days depending on design complexity. Rush production options may be available upon request.
Do you offer eco-friendly material options?
Yes. We supply GRS-certified recycled plastics and biodegradable acetate for brands prioritizing sustainability. All eco materials comply with REACH and RoHS international standards.
What are your standard shipping terms?
We operate under FOB (Shenzhen / Ningbo), CIF, or DDP terms based on your logistics preference. We partner with major freight forwarders to offer competitive rates worldwide.
Can I request a sample before placing a bulk order?
Absolutely. Pre-production samples are available for a nominal fee, which is fully credited back against your bulk order. In-stock samples can be shipped within 3–5 business days.
Do you provide OEM and ODM services?
We offer both. OEM means we manufacture to your design; ODM means you choose from our catalog and we customize for your brand. Our in-house design team can assist from concept to final artwork at no extra charge.
