Marque Magnetics Engineering

Engineering

With 6 power electronic design engineers on staff, Marque Magnetics is the leading power magnetics and wound component design specialist in Australasia.

Our engineers embody our 30 years of accumulated design experience. This experience allows our engineers to design from scratch to meet your defined electrical and mechanical parameters, alternatively re-engineer a complete specification, or reverse engineer componentry. We manufacture, test and refine prototypes, and for all our designs we work closely with your engineers to ensure an optimised solution for your system. 

Our design experience includes fulfilling UL, TUV, VDE, SAA (AU/NZ), CCC & IEC safety standards, and we are able to use our UL insulation system, lowering your compliance costs.

Marque Magnetics Custom Design

Custom Design

Marque Magnetics has been designing wound components for over 30 years and this expertise is available to you.

Why use our custom design services?

Our designs start with the most cost effective and commonly available componentry on the market. We buy a very broad spectrum of components daily so we know what is available and at what cost.

We design to maximize manufacturability which impacts directly on production times. Wound components are generally very labour intensive so it pays to design them for effective production.

Our design focus is towards high efficiency performance which directly impacts power consumption, a cost factor for your end product.

We routinely deal with international electrical safety standards and know what is required for compliance.

We have a broad range of experience across many industries, insights from which your design will benefit directly.

Our capabilities include customizing bobbins, ferrite cores, laminations and the materials from which these are made.

We can do all of this much quicker and more effectively than most!

How it works:

Our engineer will study your design criteria and establish a time and cost budget for carrying out the project in full. We will need to know how many prototypes you will require for your testing programme to cost them into the project budget.

On your approval of our quotation, we will require a Purchase Order for the budgeted amount of the project. (if you do not have an account with us, you will need to pay 50% of the budgeted price up front with the final 50% paid prior to the release of prototypes).

Our commitment to you is that we will stick to the budgeted time and cost figures unless you introduce additional requirements which require more time/resources. In that case, we will discuss the additional costs with you and get your written approval before proceeding with the work.

By default we design magnetics to the IEC61558 (AS/NZ61558) safety standard but you can specify what standard you want met, such as a UL or TUV equivalent. You must specify if you require the part to be RoHS and/or WEEE compliant

Additional parts for pilot or manufacturing runs must be ordered separately as their cost is not included in the contracted design price.

We will supply an initial set of prototypes for you to test as per the quantities you requested originally. Should more be required we will proceed with them on your approval of the additional cost to make them. On your final approval of the prototypes, we will send you a full manufacturing specification and our quote for the manufacture of the product according to your expected usages.

You own your design and we will never discuss, manufacture or release your design(s) to anyone besides yourselves without your full written consent.

Marque Magnetics Manufacturing

Manufacturing

The following processes are available in both our China and New Zealand manufacturing facilities: Coil winding in all configurations,  electromechanical assembly,  vacuum encapsulation, conformal coating with epoxy, and various other materials, and PCB assembly with our magnetics.  Small quantities can be made at our New Zealand plant for testing, prototyping and initial production runs, and when required seamlessly transferred to our Chinese plant for cost effective mass production.
