Diploma in Design for Manufacturing and Assembly
Online postgraduate diploma of 800 hours in design for manufacture and assembly: 8 modules covering DFMA principles, design for plastic injection moulding, sheet metal and metal parts, design for assembly, material and process selection, risk analysis and cost improvement, with an assigned technical tutor.
Take the controls.
Run a real engineering trade-off from this field. Move the sliders, watch the model react in real time and beat the challenge.
What you will be able to do
Apply the DFMA methodology from the earliest design stages.
Design injection-moulded plastic parts that are manufacturable and dimensionally stable.
Design metal parts suited to stamping, casting and machining.
Optimise assemblies for efficient, error-free assembly.
Select materials and processes according to volume, cost and performance.
Identify risks through design and process FMEA.
Quantify the savings achieved by redesigning for manufacture.

How you'll learn
Delivered 100% online on the SEIUM campus, with downloadable material, recorded classes and an assigned technical tutor. There are no fixed timetables: you progress at your own pace within each intake, so the programme fits around your job.
Each module combines theory, guided reading of the original standard and applied exercises. The working software is Boothroyd Dewhurst DFMA, Autodesk Moldflow, Siemens NX, aPriori and Siemens Tecnomatix, in free, academic or evaluation versions. Practical work is based on real procedures: DFMA analysis of real products, filling simulation of injection-moulded parts and teardown of competitor components. Assessment is continuous by module, plus the final capstone project.
Standards covered: ISO 2768-1, ISO 20457, ISO 1101, IATF 16949, AIAG-VDA FMEA, ISO 286-1, VDI 2221.
Build it end to end
Your final project follows the real engineering workflow, step by step, reviewed by your tutor.
