About Vinamold
Vinamold® is a hot melt compound which is meltable compositions used for the preparation of flexible molds. It is an economic alternative to silicone rubber, polyurethane and rubber latex for casting concrete, gypsum, polyester resins.
Vinamold® is an established name within the industry due to the unrivalled quality and versatility. For over 30 years clients know and trust the brand named which is a cost effective material for recreating article in a variety of various materials (i.e. plaster, reconstituted stone articles, polyester, glass fiber laminates…).
A Hot Melt PVC Compound, Meticulously Crafted for Creating Flexible Moulds
Applications
Why Use Vinamold® ?
A hot melt compound based on vinyl resins for making flexible molds. Suitable for casting polyester, plaster, epoxy, and phenol-formaldehyde resins. Vinamold is flexible, melts at 302–338°F (150-170°C), and pours at 284–302°F (140-150°C). The molds are waterproof, chemical-resistant, and unaffected by climate. They capture fine details and allow multiple casts before being re-melted and reused.
Common Applications:
- Arts and crafts
- Interior decorating
- Casting detailed objects
- Ornamental designs
- Creating moulded replicas
- Three-dimensional models
Which Colour is Best for My Application?
- Red Vinamold: Softest materials, allowing for reproduction of very detailed parts and objects. Ideal for highly precise reproduction of arts & crafts parts with a high level of detail.
- White Vinamold: Combine flexibility with strength to reproduce small to medium-sized souvenirs with a good level of detail . Can be used multiple times before being replaced
- Blue Vinamold: Material with good general properties. Allowing medium to large-size interior decoration reproductions with a suitable level of detail.
- Yellow Vinamold: Hardest material specially designed for large size and/or heavy construction part reproduction.
How to use Vinamold correctly
Melting process:
Vinamold can be melted using various methods including microwaves, but for best results, we recommend using thermostatically controlled melting equipment. This ensures the material melts consistently and correctly at a stable temperature. The material should reach a liquid state without any discoloration or smoke. If overheating occurs, as indicated by these signs, the material should be discarded.
Pouring process:
After melting Vinamold, pour the molten material slowly and steadily to the required depth, ensuring a minimum coverage of 0.787 inches. To avoid trapping air, it may be necessary to maneuver the assembly, allowing the liquid to fill all details; having an assistant can be helpful. Allow the finished mold to set for at least 8 hours before attempting to release it. For intricate or smooth surfaces, this process may take longer and should involve gentle manipulation rather than tools that could cut or tear the PVC. Minor imperfections, such as air bubbles or tears, can be corrected by carefully touching up with a hot blade. If needed, small pieces of Vinamold can be fused into the mold surface to fill any cavities that may form if not properly addressed.
Safety first
When handling molten Vinamold, exercise extreme caution as it melts at temperatures above 150°C (302°F) and can cause burns. Avoid inhaling fumes during melting; although not toxic, the vapors from plasticizers can be irritating. Ensure adequate ventilation and extraction in the heating area to minimize discomfort and respiratory irritation.

Frequently asked questions about Vinamold
What is Vinamold used for?
Vinamold is used to create flexible molds for casting concrete, gypsum, plaster, polyester resins, reconstituted stone, fiberglass laminates, and other reproduction materials.
How does Vinamold work?
Vinamold is a hot-melt flexible PVC compound. It is melted, poured around the master or pattern, cooled into a flexible mold, and then reused for casting reproductions.
When should I choose Vinamold instead of silicone or latex?
Choose Vinamold when the project needs a cost-effective reusable mold material for detailed reproductions, larger molds, or repeated casting where hot-melt processing is acceptable.
Can Vinamold be reused?
Yes. Vinamold is reusable and can be remelted for future molds, making it an economical option for repeated casting and mold-making work.
Which Vinamold grade should I choose?
Choose the grade around the project: red for high-detail reproductions, yellow for large reproduction sizes, white for multiple reuses, and blue as a balanced compromise across features.
Can Vinamold be used for small and large molds?
Yes. Vinamold can be used for both small detailed molds and larger reproductions, including molds up to several meters depending on the grade and project setup.
What makes Vinamold cost effective?
Vinamold is cost effective because it can be reused, remelted, and selected by grade for the reproduction need, reducing waste and supporting repeated mold-making work.
