Strain Relief and Other Benefits to Low-Pressure Molding
Low-pressure molding (LPM) is a practical molding process with a wide range of uses. It’s capable of achieving better cable protection, superior sealing, and enhanced productivity compared to the materials commonly used in the sealing process, like potting silicones or resins, for example.
This noteworthy process has a plethora of benefits, making it a go-to choice for encapsulating and protecting electronic components. Whether it is against dirt, dust, moisture, or vibration. If you want to know the sheer impact of low pressure overmolding and the benefits it can offer, you’ve come to the right place. We prepared a list of what LPM can offer for cable assemblies.
- Strain Relief
When thinking about cable strain solutions, the first thing that comes to mind is low-pressure molding. LPM is widely used for wiring. Technomelt features adhesive compounds, allowing it to bond to casings and wire jackets.
By positioning the bundle, cable, or wire in the mold tool, the potent plastic feature with predesigned lugs or holes will be fixed to the wiring. While the exposed joints remain enclosed. Because of the low injection pressure, which is basically its highlighted feature, LPM doesn’t damage the components. Even when working with delicate or fragile components.
- Enhances Productivity
LPM is a clean and simple process with a 10 to 50 seconds cycle time. Because of its high flexibility of shielding countless electronic products, it makes for an efficient, productive, and very functional method of manufacturing.
It features superior material properties with excellent water resistance and electric insulation. Due to its chemical resistance, the molding products become resistant to alkalis, acids, alcohol, oils, and gasoline. Another one of its key characteristics is its thermal durability.
It has from -40 °C to +150 °C temperature resistance, which adds another layer of versatility and convenience. Simply put, low-pressure overmolding ensures the long-term reliability of every electronic component.
- Common Applications
One of the primary reasons why people opt for LPM cable protection is because it has numerous applications. It can create high-quality products with ease. These uses include:
- Consumer Electronics
- LED lighting
- Camera modules
- Automotive sensors and switch electronics
- Solar inverters
- Power supplies
This process uses great precision, allowing it to work with high-stake and sensitive electronics. The final products are temperature resistant, watertight, and lightweight. Furthermore, they are a lot more customizable, which gives them a better general appearance. Since you won’t need any fillers, the molds are a more practical choice. But, you still get a durable product.
- No Scrap
The polyamides are almost 100% reusable. This makes it a highly sustainable process with minimal waste. Those who prefer to think about the environmental impact often turn to low-pressure over-molding. It doesn’t produce harmful fumes and has a long shelf life.
- Fits a Tight Budget
Although the costs of initial materials may reach a steep price, users can acquire countless cost-effective measures during the manufacturing process. That makes it a great choice for a tight budget. For instance, molds used during injection molding that require extreme heavy-duty steel are expensive.
With LPM, you can use affordable aluminum molds or 3D printed models capable of prototyping various iterations. Besides, aluminum gets rid of the heat faster when the process is over. This also reduces the overall cycle time. Not only is it a more efficient solution for heat distortion, but it is also lighter on the wallet.
LPM can simplify your manufacturing process. Not only is it a more cost-effective solution, but it is also sustainable, efficient, and has plenty of flexibility. Options such as these make it a favorable process in the manufacturing industry.
