Manufacturing Hurdles for Nashua Innovators
Nashua businesses often face a common set of obstacles that can stall growth and inflate budgets. Because the region is a hub for high-tech innovation, the margin for error is razor-thin. If you are experiencing any of the following, your current manufacturing strategy may be at risk:
1. The Prototyping Gap
Many Nashua startups find that while 3D printing is great for initial concepts, it fails to simulate the structural integrity of a molded part. This leads to unexpected failures during late-stage stress testing or when exposed to New Hampshire’s rugged environmental conditions.
2. Fragmentation of Services
Sourcing a molder in one location and an assembly house in another creates a logistical nightmare. Fragmented supply chains lead to finger-pointing when parts don’t fit, increased shipping costs, and significant delays in reaching the market.
3. Material Instability
New Hampshire’s climate—ranging from high-humidity summers to sub-zero winters—can be brutal on inferior plastics. Parts that aren’t engineered for specific thermal expansion rates or UV stability often warp, crack, or lose their aesthetic appeal shortly after deployment.
4. Quality Control Blind Spots
Without rigorous plastic testing and inspection services, microscopic defects like internal voids or weak knit lines go unnoticed until the product is in the customer’s hands, leading to costly recalls and brand damage.
