Guide to manufacture durable smart door lock enclosures

Smart door locks have revolutionised and transformed the way individuals use door locks all across the world. Smart locks have enabled remote access for properties, enhanced home security, prevented burglaries, opened new business opportunities for property owners, are reprogrammable and responsible for numerous other benefits.

While the market for smart door locks is expanding, companies are fighting to create functional and aesthetic smart door locks to win over a larger market share. While designing and planning to manufacture these locks, selecting the right door lock enclosure is one of the most crucial decisions.

The enclosure plays a big role in the success of these locks, and this blog is all about guiding you to make the right decisions for your door biometric lock enclosure.

Steps to choose the right door lock enclosure

#1 – Design (DfM feedback) based on aesthetics and manufacturing

DfM analysis done by manufacturing experts should be the first step to ensure the smart enclosure’s design is best suited to the purpose of the smart lock. Factors that the design should be optimised for must include:

  • Minimal space-taking structure while having enough space for components
  • Space for connections and other components (if any)
  • Aesthetic build of the enclosure
  • Complexity based on the manufacturing process (like 3D printinginjection moulding, etc.)
  • Material analysis
  • And a few other factors

#2 – Material and cost

Your fingerprint door lock enclosure’s material impacts cost, compliance, design, and every other success factor. Certain materials would make more sense than others based on factors such as temperature resistance, waterproof factor, signal transmission, cost, and others.

Certain examples of materials include different types of metals, ABS plastic, polycarbonate, and others.

#3 – Compliance and protection

Based on the end-use case and the country where it might get used, companies must also take care of compliance requirements. Certain certifications that you should consider are:

  • IP rating (Mostly used to determine water and solid particles ingress)
  • NEMA ratings (Mostly used for ingress and durability)
  • UL ratings (For fire)
  • RoHS compliance (To prevent the use of hazardous materials in manufacturing)

#4 – Durability and strength of the enclosure

Other factors that must be considered for manufacturing enclosures:

  • Rigidity
  • Temperature resistance
  • Electrical insulation (based on requirements)
  • Signal transmission
  • Chemical resistance
  • Scratch and stain resistance
  • Scope for future changes
  • And other factors

#5 – PCB support

The printed circuit board (PCB) is one of the most important components of your electronic door lock. The enclosure size, material, and shape should be made while considering the position and safety of the PCB.
