If you’re in the market for injection molding hollow parts, you’ve come to the right place. As a seasoned injection molding hollow part manufacturer, LXG Mold Tooling understands the challenges, the design nuances, and the technical demands that accompany hollow geometries. In this article, I’ll walk you through how we handle hollow part injection molding, why choosing the right injection mold hollow parts factory matters, and what to look for when selecting an injection molding hollow parts supplier. By the end, you’ll know why LXG Mold Tooling is an ideal partner to bring your hollow-part designs into real life — reliably and at scale.
Why Hollow Parts Are Special (And Challenging)
When you ask a plastic molder to produce hollow parts — think containers, housings with internal cavities, fluid conduits, double-wall enclosures, etc. — you’re asking for more than a simple solid geometry. Hollow parts come with unique challenges:
Wall balance & uniform thickness — Uneven walls lead to warpage, sink marks, or even structural weaknesses.
Flow paths & venting — Getting molten plastic to fill internal cavities evenly, with no voids or air traps, is tricky.
Gate & runner design — You often need specialized runner systems or multiple gates to feed internal spaces.
Cooling & cycle times — Hollow geometries tend to trap heat, affecting cooling rate and part quality.
Mold complexity — Cores, sliders, collapsible cores, or unscrewing mechanisms may be needed inside the mold.
Because of these complexities, not every injection molding hollow parts factory is equipped to do it well. You need a manufacturer with experience, precise tooling, and good process control. That’s where we at LXG Mold Tooling shine.
What Makes LXG Mold Tooling a Reliable Injection Molding Hollow Part Manufacturer
Here’s how we set ourselves apart as your go-to injection molding hollow parts manufacturer / supplier:
Deep Expertise in Hollow-Part Tooling
We design and build molds capable of producing hollow geometries reliably. Whether it’s injection mold hollow parts with internal cores or overmolded dual-wall designs, our tooling engineers optimize gate placement, cooling channels, venting, and material flow.
Prototype to Production Continuum
We support both low-volume runs (pilot or bridge tooling) and mass production runs — meaning we can be your injection molding hollow parts factory from day one to scaled manufacturing.
Quality & Process Control
We employ FAI inspection, CMM measurement, SPC traceability, and design reviews at every stage to ensure consistent dimensions and quality — essential for high-precision hollow parts.
Material Versatility
We handle a broad range of resins — from basic PP, ABS to advanced engineering plastics — so you’re not limited in material choice when designing hollow parts.
Tight Lead Times & Scalability
Because hollow-part designs often require iteration, we emphasize rapid tooling and fast prototyping to minimize development cycles. Once validated, we scale smoothly to higher volumes.
Customer-Focused & Transparency
We treat your IP with respect, maintain open communication, and provide detailed reports and feedback through every phase.
Typical Hollow-Part Applications & Use Cases
To give you context, here are real-world types of injection molded hollow parts we often produce and design for:
Enclosures with cavities — e.g. electronic shells where interior space must house PCBs, connectors, etc.
Double-wall containers — for insulation, strength, or fluid transport.
Fluid-carrying hollow passages — e.g. internal conduits, channels within housings.
Battery or fluid tanks — sealed hollow boxes for devices.
Caps, lids, piping connectors — parts where hollow forms are essential.
Because hollow parts are common in industries like automotive (fluid housings), medical devices (fluid pathways), consumer electronics (casing envelopes), and industrial machinery, you want a manufacturer who knows the ins and outs.
The Process for Manufacturing Hollow Parts at LXG
Here’s how we typically go from your idea to finished hollow parts, when you work with us as an injection mold hollow parts manufacturer:
1. Design Review & DFM Feedback
You provide us the CAD or 3D model. Our engineers review the design focusing on wall thickness, draft angles, flow paths, undercuts, and mounting features. We suggest changes to make the hollow part manufacturable. This step ensures fewer revisions downstream.
2. Prototype / Soft Tooling
We often build an initial prototype mold (aluminum or soft tool) to validate the hollow geometry, flow, fit, and function. This rapid tooling stage allows you to test the part in real conditions before committing to hardened tooling.
3. Mold Tooling for Hollow Parts
Once the prototype is validated, we build hardened steel molds with features such as cores, collapsible cores, side actions, and conformal cooling if needed — all designed to reliably produce injection mold hollow parts.
4. Process Setup & Validation
We run trial shots, inspect parts via CMM and other methods, tweak parameters (temperature, injection speed, pack/hold, cooling time), and optimize until we achieve stable, repeatable results.
5. Low-Volume Runs / Bridge Production
Before full-scale production, we often run small volumes to further validate consistency and let you test in your system or assembly line. If acceptable, we proceed.
6. High-Volume Production
Once validated, we lock parameters and produce larger volumes. Since the tooling is robust and the process is refined, our injection molding hollow parts factories can deliver high yield, minimal scrap, and consistent quality.
7. Post-Processing & Inspection
Depending on your needs, we do trimming, ultrasonic welding, insert molding, assembly, labeling, testing, and 100% inspections if required.
8. Packaging & Deliveries
We pack carefully (bubble wraps, custom trays, etc.) and ship globally. As a supplier, we take care of logistics so your parts arrive safely.

Choosing an Injection Molding Hollow Parts Supplier: What to Look For
When you’re ready to pick your supplier or manufacturer, here are the key criteria to evaluate:
Experience with hollow geometries — Not every molder does internal cores or double walls well.
Tooling capability — In-house mold shop, skilled tooling engineers, advanced machinery.
Quality systems — FAI, SPC, CMM, ISO certifications.
Material support — Ability to mold not just commodity thermoplastics but also engineering grades.
Scalability & flexibility — From prototype to mass — no major retool delays.
Communication & transparency — Frequent updates, early warning of issues, open DFM feedback.
Lead times & delivery track record — How often do they meet deadlines?
Intellectual property security — Ensure your designs are safe.
After-sales support & service — Mold maintenance, troubleshooting, spare parts support.
Price vs value — Lowest price isn’t best if quality or reliability suffers.
If a supplier checks all these boxes, you’re in good hands.

Real-World Example (Hypothetical)
To help you visualize, here’s a hypothetical (but realistic) example:
You’re designing a double-walled container with an internal cavity for fluid flow. You send us your CAD. We suggest slight changes to ensure uniform wall thickness, add thin ribs for stiffness, and propose gate locations.
We build a soft prototype mold, you test it, find minor issues, we fine-tune, then build the hardened mold. We optimize the injection parameters, run pilot batches, deliver 1,000 units for your testing. Once all checks pass, we ramp up to 100,000 units.
Throughout, you get inspection reports, photos, and real-time feedback. You only communicate with a dedicated project manager. You’re stress-free — we deliver quality hollow parts reliably.
That’s how we as an injection molding hollow parts manufacturer operate.
FAQ for Prospective Clients
Q. Can all hollow parts be made with injection molding?
Most can, but certain extremely large, extremely thin-walled, or oddly shaped parts might be better made with blow molding or rotational molding. We’ll help you evaluate the best approach.
Q. How much does a hollow part mold cost?
It depends on complexity. Simple cavity/ core molds are on the lower side; molds with collapsible cores, side actions, or unscrewing features cost more. We quote transparently.
Q. What tolerances can you maintain?
We can reliably maintain ±0.05 mm or better on many parts, depending on complexity, material, and wall thickness.
Q. How many cavities can your molds have?
We design single, multi-cavity, and family molds depending on volume needs.
Q. What is your minimum order quantity (MOQ)?
We believe in flexibility. Our MOQ is minimal, so you can start small and scale as you gain confidence.
