| Factory Advantage | Effectively molding Elastollan 1195A for IP68-rated action camera housings hinges on controlling its hygroscopic nature and high melt viscosity. Our process begins with mandatory, strictly monitored pre-drying to prevent hydrolysis that leads to surface porosity. The key to achieving a net-shape, defect-free sealing surface in a single step lies in our Yizumi UN-V5 160T press. Its high-rigidity V-shaped toggle clamping system provides exceptional platen stability under the high pressures required for this TPU. This minimizes mold deflection, preventing flash and ensuring consistent cavity filling. The resulting shot-to-shot repeatability at MechanoFab guarantees components with zero microscopic porosity on critical sealing faces, directly meeting the IP68 standard without any secondary finishing operations. |

Technical Deep Dive
Action Cameras & Gimbals Elastollan 1195A Standard Injection Molding with Yizumi UN-V5 160T
As a senior engineer, you understand that the products you design live and die by their weakest link. For the demanding world of Action Cameras & Gimbals, the battlefield is unforgiving. Your device will be dropped, submerged, covered in dust, and vibrated to its limits. The user doesn't care about durometer ratings or melt flow indices; they care about capturing the moment, whether it's 30 meters underwater or strapped to the handlebars of a downhill mountain bike. The burden of that reliability falls squarely on the manufacturing process, and specifically, on the integrity of the housing. This is where most projects introduce unacceptable risk, and it’s a problem we have systematically engineered to solve.
The challenge is a classic engineering trade-off. You need a material that is tough enough to withstand impacts, flexible enough to form a reliable seal, and resistant to abrasion. BASF Elastollan 1195A, a high-performance thermoplastic polyurethane (TPU), is an obvious first-choice material on paper. Its 95A hardness and 45 MPa tensile strength are exactly what you need to survive the rigors of MIL-STD-810G. However, this material is notoriously difficult to process correctly. It is intensely hygroscopic, meaning it acts like a sponge for ambient moisture, and it possesses a high melt viscosity, making it stubborn to inject. Attempting to mold this material using a generic Standard Injection Molding setup is a direct path to field failures. At MechanoFab, we don't just run a process; we master the intricate dance between material science and machine dynamics. By pairing our rigorous process control with the specific capabilities of the Yizumi UN-V5 160T injection molding press, we have developed a definitive manufacturing solution that produces IP68-rated housings directly from the mold, with zero secondary operations. This isn't marketing; it's a technical briefing on how we achieve manufacturing certainty for your most demanding applications.
Engineering for Extremes: Deconstructing IP68, MIL-STD-810G, and CE/FCC Compliance
Compliance standards aren't just checkboxes; they are quantifiable measures of survival. Our process is architected from the ground up to meet these standards not by chance, but by design.
IP68 (Ingress Protection): The Battle Against Micro-Porosity
An IP68 rating promises complete protection against dust and continuous submersion in water under specified pressure. For an action camera housing, this is the single most critical performance metric. The primary point of failure is almost always the seal. While many designs rely on separate o-rings or gaskets, this introduces an additional component, a potential point of assembly error, and another item on the BOM. A far more elegant and robust solution is to design the seal as an integral feature of the housing itself. This is only possible if the sealing surfaces are molded to net-shape with absolute perfection.
This is where the challenge of Elastollan 1195A becomes acute. Its hygroscopic nature means that if the raw material pellets are not meticulously dried, they carry water into the injection barrel. At melt temperatures of over 220°C, this trapped moisture instantly flashes to steam. This outgassing creates microscopic voids and bubbles within the polymer matrix—a condition known as porosity. On a critical sealing face, these pores create an interconnected network of leak paths. The part may look cosmetically perfect, but under pressure, it will fail an IP68 test.
Our solution is twofold. First, we enforce a mandatory pre-drying protocol. We don't just "bake" the material; we utilize closed-loop desiccant drying systems with real-time dew point monitoring to ensure the moisture content of the Elastollan 1195A is below the critical 0.05% threshold before it enters the press. This completely prevents hydrolysis and the formation of porosity from moisture.
Second, we address the material's high melt viscosity. Pushing this thick, honey-like molten plastic into the intricate details of a housing mold requires immense injection pressure, often approaching 190 MPa. On a lesser machine, this pressure would cause the platens holding the mold halves together to deflect or bow, even if only by a few microns. This deflection opens a gap, allowing plastic to escape the cavity (flash) and causing the sealing ribs to be under-packed and dimensionally inconsistent. The Yizumi UN-V5 160T's high-rigidity V-shaped toggle clamping system is the key. This design provides superior force distribution across the entire platen, creating exceptional stability and minimizing deflection even under maximum injection pressure. This ensures the mold stays shut, preventing flash and guaranteeing that every cavity detail, especially the critical sealing surfaces, is perfectly formed, shot after shot. The result is a component with zero microscopic porosity on its sealing faces, meeting the IP68 standard without any need for secondary finishing or separate gaskets.
MIL-STD-810G (Drop/Shock): Preserving Inherent Toughness
This standard tests a device's ability to withstand shock, vibration, and drops. The incredible impact resistance of Elastollan 1195A is a primary reason for its selection. However, the material's datasheet properties are only realized if the molding process is flawless. Internal stresses, weld lines from poor melt flow, or the previously mentioned porosity all create stress concentration points. When a device with such a compromised housing is dropped, the impact energy focuses on these weak points, leading to fracture.
Our process control directly preserves the material's inherent strength. By eliminating porosity through proper drying and ensuring a homogenous melt through optimized temperature and injection profiles, we create a part that is uniformly dense. The Yizumi's shot-to-shot repeatability (typically within ±0.15% by weight) ensures that every part produced has the same density and structural integrity. This consistency means that the part that passes your initial drop-test qualification is identical to the 25,000th part in the production run, guaranteeing that the final product can reliably survive the physical abuse defined by MIL-STD-810G.
CE/FCC (Electromagnetic Compatibility): The Foundation of Precision
While primarily related to electronics, the housing plays a crucial role in CE/FCC certification. The precise and repeatable geometry of the molded parts is essential. Internal shielding, antenna placement, and grounding points must be located exactly as designed to manage electromagnetic interference (EMI) and radio frequency interference (RFI). Any variation in the housing's internal dimensions could detune an antenna or compromise shielding effectiveness. Our ability to hold tight tolerances, typically ±0.05mm on critical features, provides the stable, predictable mechanical foundation your electrical engineers need to design and certify a compliant product with confidence.

The Economics of Precision: TCO Reduction in High-Stakes Molding
This level of process control is not an academic exercise; it has profound economic implications. Our process is optimized for production volumes between 1,000 and 25,000 units. This range represents the sweet spot where the cost of high-quality tooling is justified by the production volume, but before the scale demands multi-cavity tools or dedicated automation cells. Within this zone, the primary driver of cost is not the price per kilogram of resin or the cycle time in seconds; it is the Total Cost of Ownership (TCO), which is massively influenced by scrap, rework, and field failures.
Our methodology is a direct assault on these hidden costs. Consider the "Factory Specific Advantage" as a TCO reduction strategy:
-
Elimination of Scrap from Porosity: By implementing mandatory, monitored pre-drying, we attack the number one cause of scrap with this material. A seemingly small reduction in scrap rate from 2% to 0.1% on a 25,000-unit run means preventing the waste of nearly 500 parts, along with the associated material, machine time, and energy.
-
Elimination of Rework from Flash: The exceptional platen stability of the Yizumi press prevents mold flash. This is not a minor convenience; it is the complete removal of a costly, manual, and inconsistent post-processing step. You save on the labor cost of operators trimming parts, the floor space for a rework station, and the quality risk associated with manual processes.
-
Elimination of Secondary Components and Assembly: This is the most significant advantage. By molding a perfect, net-shape sealing surface directly into the housing, we eliminate the need for a separate o-ring or gasket. This removes a component from your BOM, simplifies your supply chain, and deletes an entire assembly step. There is no risk of a gasket being twisted, pinched, or forgotten during assembly because the seal is integral to the part itself. The part is born waterproof.
-
Reduction in QC and Inspection Overhead: The phenomenal shot-to-shot repeatability means that once the process is dialed in, it stays there. This reduces the need for extensive, part-by-part inspection, allowing QC to focus on process monitoring. You can have confidence that the first part and the last part are functionally identical.
Ultimately, our approach shifts the investment from downstream correction (rework, inspection, warranty claims) to upstream prevention (process control, superior equipment). This results in a dramatically lower TCO and, more importantly, a reliable and robust product that protects your brand's reputation in the field.
When your product's survival depends on keeping the elements out, you cannot afford to leave your manufacturing process to chance. We have engineered the variables out of molding this challenging, high-performance material. Let's build something indestructible together.
