Diploma in Trim Processes, Joining and Perceived Quality
Online postgraduate diploma of 800 hours in trim processes, joining and perceived quality: 8 modules covering interior trim components, trim manufacturing processes, joining technologies, perceived quality, decorative surfaces (VDA 16), process quality (IATF 16949, VDA 6.3) and squeak and rattle, with an assigned technical tutor.
Diploma in Trim Processes, Joining and Perceived Quality — studying from Singapore
Singapore's product design sector serves consumer electronics, medical devices, industrial equipment and digital services, with strong demand for user experience and interface design. The Singapore University of Technology and Design runs design-focused programmes, and the Design Singapore Council promotes design capability across industries. Engineers working in human-machine interface design combine usability research with embedded and software development. Employers include multinational product companies, technology start-ups and design consultancies.
Fees for Singapore: S$1,560 (Singapore dollar), with instalments and employer sponsorship available.

Questions from Singapore
Is product or HMI design a regulated profession in Singapore, and is SEIUM recognised?
Product and HMI design is not a licensed profession in Singapore, so there is no statutory registration. Relevant bodies include the Singapore Institute of Architects for some design work and the Design Singapore Council for industry promotion. SEIUM's qualifications are private, not state degrees, and not accredited by any national body, so recognition is decided by employers.
Which Singapore employers hire HMI and product design engineers?
Opportunities exist with electronics and medical device firms, consumer product companies, software houses, and automotive and industrial suppliers. Singapore's manufacturing and healthtech sectors are notable employers. Hiring managers usually look closely at design portfolios and user research work. Your final project can strengthen your portfolio, though employers judge it on their own terms.
Can I study this alongside work from Singapore, and what are the payment options?
Yes, all programmes are online and taught in English, so you can study from Singapore without a student visa and fit lessons around work. The workload is significant, with 1,900 hours for a master's, 800 for a postgraduate diploma and 300 for a specialist course. Fees can be paid in instalments, and employer sponsorship is possible.

How you'll learn
100% online training on the SEIUM campus, with downloadable material, recorded classes and an assigned technical tutor. There is no fixed timetable: you progress at your own pace within the intake, so the programme is compatible with work.
Each module combines theory, guided reading of the original standard and applied exercises. The working software is CATIA V5, Siemens NX, Autodesk Moldflow, Minitab and Polyworks, in free, academic or evaluation versions. Testing is studied through real procedures for perceived quality audits in a light booth, pull-out tests on clips and joints, and squeak and rattle tests on a shaker table. Assessment is continuous by module plus the final project.
Standards covered: IATF 16949, VDA 16, VDA 6.3, ISO 9001, UNECE R21, FMVSS 302, ISO 1101.
Build it end to end
Your final project follows the real engineering workflow, step by step, reviewed by your tutor.
