Plastic CNC Machining
CNC machining, or Computer Numerical Control machining, is a manufacturing process that utilizes computerized controls to operate and manipulate machine tools.
Injection Molding
Injection molding is a cornerstone of mass production, balancing efficiency, precision, and versatility.
Prototype to Production
From prototype to production: CNC validation, then injection molding for scalable, cost-efficient parts.

Frequently Asked Questions
1. What materials do you machine?
We specialize in high-performance engineering plastics, including PEEK, PTFE, POM (Delrin), Ultem, Nylon, and PPS. With 17 years of experience, we have refined our processes to handle these materials’ unique properties, such as PEEK’s high-temperature resistance (up to 260°C) and PTFE’s chemical inertness.
2. What tolerances can you achieve?
Our precision CNC machining centers can hold tolerances as tight as ±0.001 inches (0.025 mm) for critical dimensions, depending on material and part geometry. For example, we routinely achieve ±0.002 inches on PEEK components for semiconductor applications.
3. What is your typical lead time?
Standard lead times range from 2 to 4 weeks for most orders, with expedited options available for urgent projects. Over 90% of our orders ship on or before the quoted delivery date, backed by our ISO 9001:2015 certified production scheduling.
4. Do you accept small orders?
Yes, we accept orders of any quantity, from single prototypes to high-volume production runs. Our flexible setup allows us to efficiently machine as few as 1 to 5 parts for R&D or low-volume medical device needs.
5. What certifications do you have?
LELAND TECHNOLOGY is ISO 9001:2015 certified, ensuring our quality management system meets rigorous international standards. This certification is audited annually and covers all our machining processes for the semiconductor, medical, aerospace, and automotive industries.
6. Which industries do you serve?
We serve four primary industries: semiconductor, medical, aerospace, and automotive. For example, we machine Ultem and PPS components for semiconductor wafer handling equipment, and PEEK parts for medical implants and surgical instruments.
7. How do you ensure quality?
Quality is ensured through a multi-step inspection process, including in-process checks and final CMM (Coordinate Measuring Machine) verification for critical features. Our ISO 9001:2015 system mandates documented traceability for every batch, with a typical first-pass yield exceeding 98%.
8. How can I get a quote?
You can request a quote by uploading your 2D drawing or 3D CAD file (STEP or IGES format) through our “Get a Quote” page. Most quotes are provided within 24 hours during business days, including material selection advice and tolerance analysis.
