Estimates for a small start in the UK, not guarantees.

What it is

A specialist web shop stocking materials for making and using moulds, such as silicone rubber, casting resin, release agents, mould boxes and pigments. You buy in bulk from manufacturers or wholesalers and repack or resell in smaller sizes.

Your first three steps

  1. Pick a niche, such as silicone and resin for small makers, and get trade price lists from several UK suppliers
  2. Order sample stock, test the products yourself and write clear guides for buyers
  3. Set up a simple online shop and offer a few launch bundles to maker groups and workshops
Who pays

Small manufacturers, prop and model makers, jewellery and homeware makers, and workshops that need small to medium amounts of material.

How it makes money

Mark-up on products bought in bulk, plus extra margin on repacked smaller sizes, starter kits and delivery charges. Repeat orders from regular customers are the core of the business.

Questions people ask

How much does it cost to start an online mould-making supplies shop?

Startup costs are typically around £3,000 to £12,000, depending on the range you stock and how much bulk material you buy. Cash gets tied up in stock, so it helps to start with a small range.

How much can an online moulding supplies shop make?

Monthly revenue is typically estimated at around £1,500 to £7,000, depending on your range, pricing and how many makers and workshops you reach. That is revenue rather than profit, so allow for stock, packaging and delivery costs.

What rules should I check before selling resins and chemicals online?

Check COSHH, CLP and REACH requirements for labelling, storage and safety data sheets. Also check courier restrictions or extra charges for chemicals before promising delivery, and look at product and public liability insurance and where to store stock safely.
