D.L. Martin engineering and quality departments are certified ISO entities of the Company’s ISO 9001 - 2008 system. Level 1 government program certification denotes a high performing quality program.

Engineering experience in the elevator industry, mining industries, hydraulic systems, and other complex markets, serves a diverse customer base.  Finite Element Analysis (FEA) and Fluid Flow simulation and analysis, full prototyping, and design assistance are skills available to every customer.

Unique capabilities include recognized global excellence in engineering of variable dimension and custom product lines using programmed DriveWorks solutions.

SolidWorks software is the primary design tool, but D.L. Martin also has a complete set of the latest Computer Aided Design (CAD) file capabilities.

Our manufacturing engineering team uses MasterCam for programming and to import solid models for reduced customer programming time. Direct Numerical Control (DNC) connections are used to communicate with all Computer Numerical Control (CNC) machines.

Engineering FAQs

Are both DLM Mercersburg an DLM East Berlin ISO Certified?
What is ISO 9000?
ISO 9000 is defined as a certification showing that a manufacturing or service organization follows the standards from the International Organization for Standardization (ISO) , which call for strong management, product development documentation and quality customer service practices.
What is ISO 14000?
ISO 14000 is a family of standards related to environmental management that exists to help organizations minimize how their operations (processes etc.) negatively affect the environment.
What is lean manufacturing?
Lean manufacturing or lean production, often simply "lean", is a systematic method for the elimination of waste within a manufacturing system.
What is the difference between lean manufacturing and JIT (Just-in-Time) Manufacturing?
Lean manufacturing or lean production, often simply "lean", is a systematic method for the elimination of waste within a manufacturing system.
What is APQP?
APQP is a structured approach to product and process design. This framework is a standardized set of quality requirements that enable suppliers to design a product that satisfies the customer.
What is the goal of APQP?
The primary goal of product quality planning is to facilitate communication and collaboration between engineering activities. APQP ensures the Voice of the Customer (VOC) is clearly understood, translated into requirements, technical specifications and special characteristics. APQP supports the early identification of change, both intentional and incidental and supports the never-ending pursuit of continuous improvement.
What is a PPAP?
The PPAP, or Production Part Approval Process, is a plan to ensure consistent quality in the creation of a part. The primary goal of this control plan is to identify, quickly counter, and factor all that could alter the specifications and production tolerance for a given part.
What are the 18 elements of a PPAP?
Design Documentation, Engineering Change Documentation, Customer Engineering Approval, Design Failure Mode and Effects Analysis, Process Flow Diagram, Process Failure Mode and Effects Analysis, Control Plan, Measurement System Analysis Studies, Dimensional Results, Records of Material / Performance Tests, Initial Process Studies, Qualified Laboratory Documentation, Appearance Approval Report, Sample Production Parts, Master Sample, Checking Aids, Customer Specific Requirements, and Part Submission Warrant.
