Injection molded polycarbonate chocolate molds

Micelli specializes in the design and production of INJECTION MOLDED polycarbonate chocolate molds. If you’re manufacturing high quality chocolate with a precise design and you want molds that can last beyond the life cycle of your product, polycarbonate injection molds are the industry standard.

The combination of rigid flat surfaces, ultrafine engravings, high quality surface finish, and extreme durability make injection molds the perfect fit for your mold requirements. We are the only manufacturer in the USA who uses the injection molding process to create the highest quality most sought after Artisan molds.

Clean Crisp Features

From your first batch to the last, your details and finish can remain precise and exact ­ visually exemplifying the quality product to your consumer. With our polycarbonate injection molds achieving the highest quality and durability possible for artisanal chocolate manufacturers, you can be confident that your chocolate will have the same clean edges and detail years and years from now. Choosing our highest quality injection molding process means a flat rigid mold, fine details, perfectly straight lines, curves that intersect at tight tangents, your molds by Micelli will deliver flawless execution day after day after month after year.

Quality Molds, Built to Last

Built to last a lifetime – unlike starter molds, our custom polycarbonate injection molds can last for decades of Artisanal use and are durable enough to withstand **dishwashers, and constant heating and cooling. We hope the only reason you come back to Micelli is because you’re increasing your production size or rolling out a new size or design.

The one time cost of the highest quality polycarbonate injection molds is worth the years of confidence and avoiding the pitfalls of inferior molds which include warping and distortion, cracking, lack of detail and finish. Know that you need to make your molds once and never worry about them again, like our thousands of prior satisfied customers.

Superior Finish

The quality of the mold has a huge impact on the smoothness of the chocolate’s surface. The injection molding process involves injecting liquid polycarbonate under extreme pressure into a steel die forming the highest quality surface. Polycarbonate injection molds are also able to far better handle heating and cooling cycles without damage, also making them **dishwasher-safe. By choosing cheaper, inferior molds, manufactured by thermoforming/ vacuum forming or use of PET plastics will result in eventual warpage or damage the finish.

**Keep surface temperature below 150F and use proper detergents

The difference between Injection Molding and Vacuum Forming is Quality and Durability

First let’s demystify the term polycarbonate. Polycarbonate is a type of plastic, not a method of construction or manufacture. Therefore even if polycarbonate plastic is used in the vacuum/thermoforming process they will still possess most of the shortcoming of the vacuum/thermoforming process. Just because it is made with polycarbonate plastic or called a "polycarbonate mold" doesn’t make it a high quality Micelli injection molded polycarbonate chocolate mold. Be informed – ask specifically for "injection molded" polycarbonate chocolate molds.

High Quality Polycarbonate Injection Molds by Micelli

Injection Molding Process

  • Injection molding is used to produce the most sought after molds for specialty Artisans chocolatiers and bean to bar manufacturers.
  • Plastic polycarbonate pellets are melted at very high temperature above 500 degrees F.
  • Molten plastic is injected in liquid form into a 2 part steel/alloy metal die under extreme pressure (upwards of 20,000 PSI).
  • Finished molds ejected from the steel mold and are a rigid, stable, extremely durable product.
  • Plastic type is exclusively polycarbonate in our injection molding process for chocolate molds.
  • Advantages- Very fine details, sharp images, superior surface finish & textures, rigid flat top surface, longest mold life(avoids replacements), ability to be used on automatic depositors/molding lines, washable in dishwashers /industrial washers.

Vacuum/Thermoforming Process

  • This is a process of manufacturing that is used to produce lower grade chocolate molds, prototype molds or molds for the craft industry.
  • Plastic starts as a sheet and is suctioned over a positive die under relatively low pressure 15 to 60 psi.
  • Plastic type can be PET or polycarbonate.
  • Disadvantages — unstable inconsistent surfaces, not flat/wavy top and sides, not sturdy/rigid, much shorter mold life, limited detail, inferior surface finish, low rigidity, low tolerance for repetitive heating/cooling cycles.
