How Does Low Pressure Molding Add Values To Your Manufacturing Process？
On October 25th, 2021, the tycoon of electric car, Tesla, surpassed a market value of $10 million. The EVs market value is estimated to be $2 trillion soon. The global market size is projected to grow from $20 billion in 2020 to $73.2 billion in 2026.
The prospect of the EVs industry is promising that relevant technologies are given to attention, including vehicles, drones, GPS, and the demands of component waterproof/harsh environment ability are increasing.
In the last few years, the low-pressure-injection molding has been popular in various sectors. For example, industrial applications, military, medical, outdoor devices, light, consumer electronics, e-bike, etc. Comparing to plastic injection molding, it features:
- materials based on renewable
- short cycle time
- no required housing
A long-partnership customer recently needed a communication cable featuring waterproof, drop-off, dust-proof, and weathering-resistance. The customer asked not to achieve the features by structural design.
The original idea was to use an O-ring. But considering the materials, it might be fragile quickly, takes long development time, and will charge an additional housing fee. We suggested the solution of LPM which features the above request and not additional mechanical structures. Additionally, it saved cost and had shorter cycle time.
During the case, we received the shut-off problem from the client. After rechecking the design layout, the R&D team found that the original thickness wasn't sufficient to encapsulate the component. To fix this problem, we amended the cable design and made sure the cable is well encapsulated.
As for the toughness of the materials, the client has a high-quality demand. Common materials couldn’t meet the demand. Hence, we looked for various materials, also validated by dropping tests. As a result, a material with much more resilient replaced the original one.
Because of the special requirement, the gasket must be removed from the design that it would make the component have less protection. It's not easy for the R&D team. Without the gasket, the electronic component couldn’t endure the external stress. In the end, we proposed the solution by changing the materials that was capable to withstand more force. In the meantime, the team redesigned the mechanism to improve the mechanical capacity to reach the client's demand.
Saving the cost, and creating a reliable link between customers and COMOSS are what we constantly work in.
