Good Design
Demoulds Clean.
Custom moulds are the line between a hobbyist bar of soap and a product line worth selling. You can absolutely figure this out alone — most makers do, eventually, after a year of failed pours and a drawer full of unusable silicone. This guide is the shortcut. The structure. The reason your fifth pour looks like everyone else's fiftieth.
It's the first release in the HXLY Product Lab series — with soap formulas, candle formulas, branding, and packaging guides to follow. Mould-making is the foundation everything else gets poured into. Get it right once, and the rest of your product line gets easier.
Four Steps. Zero Guesswork.
Plan Before You Sculpt
Silhouette, undercuts, base stability, demould direction. Get these decisions right on paper and you stop wasting silicone on shapes that were never going to release cleanly.
Sculpt, Source, Or 3D Print
Hand-sculpt in sulfur-free oil clay, repurpose existing objects, or refine a 3D print. All three pathways are covered — so you can start with whatever skills and tools you already have.
Tray Style Or Two-Part
Platinum cure silicone, Shore A 10 to 20, exact mixing ratios, registration keys, vent channels — the technical detail beginners usually have to learn the hard way, laid out in plain language.
The Part Most People Rush
Cure times, peel technique, trimming, and care — so your moulds last hundreds of pours instead of tearing on pour number five and sending you back to the supplier.
Cure Inhibition Decoded
The four materials that quietly kill a platinum cure pour, why your silicone is refusing to set, and how to diagnose it in under a minute. One chapter saves a hundred dollars in wasted product.
The HXLY Cheat Sheets
Vetted supplier categories, tool kits, and material checklists so you buy the right thing the first time — instead of returning a cart of products that don't work together.
11 Chapters.
One Studio
In Your Pocket.
Every chapter ends with something you can hold in your hands. Read it, do it, return to it. The guide is non-linear and indexed — so it works as a learning path now, and a studio reference for every product line you launch later.

Designed To Be Read,
Not Skimmed.
Editorial layouts you'll actually want to spend time in. Step-by-step diagrams that replace ten browser tabs. Pro tips placed where you'll need them, not where they look good in a marketing screenshot.
Optimised for desktop, tablet, and phone — and clean enough to print as a physical studio reference. The kind of guide you keep open while you work, not the kind you skim once and forget.
Why Platinum
Cure. Why
Shore A 10–20.
Most beginners spend their first hundred dollars on the wrong silicone, the wrong clay, and the wrong release agent — then quietly assume mould-making isn't for them. It is. The materials just weren't.
- Platinum cure (addition cure) silicone — and the few times tin cure is genuinely the right call
- Shore A 10 for fine detail, Shore A 20 for trays — when each one earns its place in your kit
- The four materials quietly inhibiting your cure (and why your last pour didn't set)
- Sulfur-free oil clay — the only clay we recommend, with the science behind why
- Mixing ratios, pour streams, and the bubble-killer technique that makes pours look professional

Questions.
Still weighing it up? Email hello@hxly.studio and a real human replies within one business day. No bots, no chase-up funnels, no AI loops — just a straight answer so you can make the call.
I've never made a mould before. Will I keep up?
Yes. The guide assumes zero prior experience and is written for makers who want a clear, confident path before they spend money on materials. Chapter 02 starts at "what is silicone, actually," so you're set up safely before any pour. If you've already touched silicone, skip ahead — the guide is indexed for fast reference.
Does this teach soap or candle recipes?
No — and that's deliberate. Mould-making is the foundation everything else gets poured into, so it deserves a guide of its own. Soap and candle formulas are the next two HXLY Product Lab drops and are included automatically in the Founder Bundle and Product Lab tiers.
What format is the guide?
An editorial-style PDF, designed to feel like a premium reference rather than a downloadable worksheet. Read it on desktop, tablet, or phone, print it for your studio wall, or drop it onto an iPad you keep next to your pour station.
How much will tools and silicone cost me?
A solid starter kit — clay, basic tools, and enough silicone for two real test pours — sits around $120–250 USD depending on supplier and region. The cheat sheets inside the guide tell you exactly what to buy first, so you spend that budget once instead of three times.
Is there a refund policy?
Yes. If the guide doesn't earn its place in your studio within 14 days, email us for a full refund. No survey, no friction, no convincing. We'd rather have one real customer than ten reluctant ones.
Do I get future updates?
Always. Every buyer gets every revision of this guide for life. As suppliers, materials, and best practice evolve, the guide evolves with them — so you're never stuck with information that's six months out of date.
You're Not Just
Making Moulds.
You're Building
Product Identity.
Skip the year of guesswork. Skip the wasted silicone. Get the system that turns your first sketch into a brand-worthy, launch-ready product line — and stays useful for every collection that follows.
