Unlike the overabundance of trading businesses in China who manufacture nothing, Leda has valuable experience manufacturing its own products out of China.

If there are products you want externally sourced then we are able to offer the very important services of engineering, manufacturing checks, quality assurance, packaging and container packing. Any business that contemplates using Chinese suppliers should know the importance these additional services will have to the overall success of this type of supply chain. One part fails and the process fails. We learnt this from experience prior to establishing our Australian owned factory in Ningbo back in 2011.

FAQs about OEM manufacturing & metal fabrication with Leda Security Contract Manufacturing

Leda Security is a proud company of ARA Group, a wholly Australian owned company. We have no local control other than adhering to regulations of China.

Predominantly Solidworks. We can also use inventor and similar.

Many western businesses are used to 30 day or more trading terms. This system does not work in China. You have to fund your own work so get used to it if you want to source in China. Leda typically ask for 50% deposit and 50% prior to shipping or supply of bill of lading.

Mainly US$ but where government agreements are in place with China we can work in and settle in your local currency or CNY / RMB. Australia is a good example of that. Internally within China everything is done in local CNY so US$ just comes up at the time of export.

Yes but understand how the tax system works in China. Exporters get a tax rebate so they can effectively offer the goods cheaper for export than they can sell locally. They are incentivised to do this so are sometimes reluctant to

We warrant our standards of assembly (precision, welds, coatings etc) however, if the product has been designed by you then warranty terms must be negotiated on a product-by-product basis. Leda warrants all goods against being packed incorrectly and scratched in transit. We take pictures of goods and packing before, during and after container packing so there is an audit trail.

Yes we can organise freight and couriers. Note that an invoice has to go with the goods. We can use your RRP pricing in this instance if this helps.

Leda has manufactured in Australia since 1995. Leda’s factory in Ningbo China commenced operation in 2011.

Coming from the Security Industry we understand the importance of confidentiality better than most. Leda will of course sign confidentiality agreements. By using multiple suppliers and assembling inhouse minimise how much IP is exposed to any single supplier. Our computing systems are also maintained both inside and outside China to minimise the risk of security breaches.

We do a lot of printed cardboard packing. We can work with your marketing people on packaging options. We have also printed catalogues locally so we can combine these in your shipments, if required..

MIG, TIG and aluminium. We can do non-structural and structural welding also although we may outsource to an approved shop to ensure adherence to your local welding accreditation. Most welding is non structural so not an issue to do internally.

Yes we have supplied electromechanical product.

Hot dip galvanising, powder coating and wet spray finishes. Most RAL colours are available although there are minimum order quantities associated with many colours.

Ideally you have your product design ready to go so we just contract manufacture. Should you choose, we can contribute to your design from a production perspective. We can also provide user / installation manuals and other technical services.

Leda have installed the ERP software system King-Dee which is the largest in China. It is bilingual. All our Bills of Materials are based on this system so we can track material and supplier shipments for batches if required.

United States, Europe, Canada and of course Australia.
