Diploma in Sealing, Watertightness and NVH of Joints
Online postgraduate diploma of 800 hours in sealing, watertightness and seal NVH: 8 modules covering vehicle sealing systems, elastomeric materials, seal design, watertightness to IEC 60529 and ISO 20653, seal NVH, sealing system validation and sealing for electrification, with an assigned technical tutor.
Diploma in Sealing, Watertightness and NVH of Joints — studying from Australia
Product design and human-machine interface work is important across Australian industries, from consumer goods and medical devices to mining equipment and transport systems. Designers and engineers collaborate on usability, ergonomics and visual interfaces, with growing attention to accessibility standards and user research. Australia has active design communities in Sydney, Melbourne and Brisbane, supported by universities and design agencies. Employers include manufacturers, software companies, consultancies and in-house product teams in large organisations.
Fees for Australia: A$2,850 (AUD), with instalments and employer sponsorship available.

Questions from Australia
Does a SEIUM qualification count for professional design recognition in Australia?
Australian design practice is recognised through bodies such as the Design Institute of Australia, which runs professional membership, and Engineers Australia covers engineering-related design. SEIUM's private qualifications are not accredited by these bodies. Employers and the relevant body decide whether it counts toward recognition.
Which Australian employers need HMI and product design skills?
Australia has product design studios, software companies, automotive and medical device firms, and consultancies needing interface and product designers. Employers usually look closely at your portfolio and user research work. A SEIUM qualification may complement this, but its weight is determined by each employer.
Can I study this part-time from Australia and what language level is needed?
Yes, the courses are 100% online, so you can study from home across Australia without a student visa. Teaching is in English, so you need solid English proficiency. Durations range from 300 to 1,900 hours, with an assigned technical tutor, instalment payments, and possible employer sponsorship.

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 Abaqus, Ansys Mechanical, MSC Marc, Siemens Simcenter Testlab and HEAD ArtemiS, in free, academic or evaluation versions. Practical work is based on real procedures: watertightness tests in a rain booth and by pressure decay, compression simulation of elastomeric profiles, and acoustic measurements in the wind tunnel and in the vehicle. Assessment is continuous by module, plus the final capstone project.
Standards covered: IEC 60529, ISO 20653, ISO 815-1, ISO 188, ISO 1817, ISO 5128, ISO 3795.
Build it end to end
Your final project follows the real engineering workflow, step by step, reviewed by your tutor.
