Benefits of Employing Molding and Overmolding with PCBs

Nonetheless, there is the cost aspect that you will have to consider when adding another level of protection. So, the question becomes, is it worth the investment? Anyone who raises the firmness of a PCB component with overmolding will get a better-performing and more durable system than someone who does not.

Strength

Additional flexural strength means high-traffic sections like cable exits can withstand more wear and tear and continue functioning properly. 

Toughness

Overmolding offers wall shielding around components. As a result, you will find that extreme environmental conditions such as high temperatures, water, impacts, abrasions, and other external forces do not damage them. 

Optimum Security 

Overmolding provides an extra layer of shielding against even the most deliberate outside forces. It acts as your PCB’s direct protection element. 

Ideal Performance

Overmolding helps to enhance the pull-strength and strain-relief capabilities of PCBs. 

Enhanced Protection

Overmolding helps seal off components from caustic elements like saltwater or oil. 

Aesthetic appeal

The fact is that aesthetically looking components tend to sell more. With overmolding, PCBs tend to look better and are easier to maintain and integrate. 

Customizing overmolds

The process of customizing PCBs with an overmold has several benefits: 

• It allows one to create different colors for an ideal overall wire management setup.
• It facilitates the good printing of corporate names, logos, or other branded messaging. 
• It offers different points that allow for integrating attached hardware components like a flange.
• Provides varying exit point angles like a right angle, sometimes needed to cater to a project’s needs. 
• It enables the use of different overmolding materials like thermoplastics or PVCs. 
• Customization of overmolds involves employing different kinds of machines, such as the LPMS (Low-Pressure Molding System), to offer the most cost-efficient solution.
