Summit by Fathom //
Turn Your Complex Part Designs into Reality,
Quickly & Efficiently
As an engineer, you’re under pressure to deliver complex, innovative products faster and more efficiently. Your expertise is in creating exceptional designs. But the path from CAD file to production-ready parts is filled with potential pitfalls: Material selection challenges. Tool design complexities. Production delays. Quality inconsistencies. Budget overruns. And more.
That’s where having the right injection molding partner becomes critical. Summit by Fathom stands apart from other injection molding manufacturers by offering an integrated approach – everything from tool design and prototyping to production and finishing – all under one roof.
Why Summit by Fathom is Your Ideal Injection Molding Partner
Our Engineering-First Approach to Injection Molding
Unlike injection molding companies that simply run parts, Fathom provides you with a real engineering team that collaborates with you throughout your project lifecycle. We don’t just quote your project. We analyze it, offering meaningful DFM feedback that can save significant time and money down the road.
Our expert team will:
- Review your part geometry for manufacturability
- Identify potential molding challenges before they become problems
- Recommend optimal material selections based on your performance requirements
- Propose tooling strategies aligned with your production needs
- Offer cost-effective solutions that don’t compromise part quality

Comprehensive Injection Molding Capabilities
Advanced Tool Building & Design
Your part design determines the type of tooling required. Our tooling expertise includes:
- Production Molds // Built for long production runs with maximum durability
- Family Molds // Produce multiple related parts in a single cycle
- MUD (Master Unit Die) Tools // Modular tooling systems for efficient part variations
- Insert Molding // Incorporating metal components directly into the molding process
- Overmolding // Combining rigid substrates with softer materials for enhanced functionality
Material Selection & Expertise
Material selection can make or break your project. Our engineers help you navigate options based on:
- Mechanical performance requirements
- Chemical resistance needs
- Temperature tolerances
- Regulatory compliance considerations
- Cost constraints
Quality Assurance Throughout Production
We maintain strict quality control measures throughout the manufacturing process:
- First article inspection and validation
- Statistical process control
- In-line quality checks
- Comprehensive documentation
- Material traceability
- Domestic Facilities
- ISO 9001 certified processes
