Every food manufacturer faces important choices around production tooling. The poor quality mold materials creates a hidden risk for end consumers. The high quality food grade silicone molds remove this entire category of risk. 

The FDA approved materials prevent the transfer of harmful chemicals to food. The non-toxic formulations meet all strict global food contact standards. Their consistent heat resistant properties maintain the exact mold shape. 

The well manufactured food grade silicone molds will not degrade during normal use. Rubber Silicone Molds specialises in certified food safe products. 

How Does Platinum Cure Silicone Differ From Standard Materials?

Platinum catalyst creates extremely stable molecular bonds. No unwanted byproducts are released during the full curing process.  

The right food grade silicone molds will operate for more than ten years. The final cured material remains completely odourless and tasteless. It offers far superior tear strength and long term durability. It lasts longer than common tin cure alternatives.

• Will not leach trace compounds into contact materials


• Does not shrink or change dimension after full cure


• Remains stable across decades of proper storage


• Requires no post cure treatment for food safe use 

The material retains full flexibility after many thousands of uses. It withstands almost all common aggressive cleaning chemicals. No other mold material offers this combination of properties. Most manufacturers now specify this material for permanent tooling. High quality food grade silicone molds use platinum cure formulation. 

Do Food Grade Molds Withstand Commercial Dishwashers?

The continuous exposure to 180°F wash cycles causes no damage. The material demonstrates proven resistance to strong alkaline detergents. The smooth surface dries very quickly to prevent bacterial growth. A properly fitted silicone rubber gasket will eliminate almost all product leakage. 

Their original shape remains unchanged after more than 1000 full wash cycles. All suitable materials carry full NSF certification for commercial kitchens. They are also fully compatible with standard steam sterilisation processes.

• Will not absorb detergent residues


• Does not develop micro cracks on the mold surface


• Leaves no film or residue on finished food products


• Requires no special treatment before or after washing 

Many lower grade alternatives will break down in under 100 cycles. A properly formulated silicone rubber gasket will show identical performance. 

Can These Molds Handle Acidic Food Products?

The material offers stable pH resistance from 2.0 right up to 11.0. Their continuous exposure to citric acid causes no breakdown or degradation. All vinegar based products are completely compatible for long term contact. 

The extended testing confirms full safety for tomato and fruit juice products. The material remains completely stable during long term exposure to acid. It resists breakdown from vitamin C and all common food preservatives. It is also fully suitable for all types of fermented food production.

• Will not discolour when exposed to strongly coloured foods


• Does not develop a stale or off odour over time


• Requires no regular reconditioning after acidic use


• Leaves no trace compounds in finished fermented products 

This is the single most common failure point for tin cure silicone. Most alternative materials will break down in less than 20 uses. The FDA silicone seals use the same base platinum cure formulation. All parts are manufactured to the same standard as FDA silicone seals.  

What Temperature Ranges Support Safe Food Production?

The material remains completely stable down to temperatures of -40°F. It can withstand continuous oven use at temperatures up to 450°F. It will tolerate short term exposure to temperatures as high as 500°F. It is fully thermal shock resistant from deep freeze to heat. Most major rubber extruder manufacturers specify this exact material formulation. 

It can be used in all standard microwaves without any damage. It withstands full autoclave sterilization at temperatures of 250°F. There is zero risk of melting or warping during normal use. Performance remains consistent across all normal temperature extremes.

• No change in hardness across the full temperature range


• Does not become brittle at very low operating temperatures


• Does not soften or stretch at high operating temperatures


• Requires no allowance for thermal expansion in design

 The product can be frozen directly inside the mold with no damage. The rubber extruder manufacturers use this same material for most food contact parts. This removes limitations from the production process design.

 Why Choose Rubber Silicone Molds for Food Production?

The company specialises in custom food grade mold design and manufacture. An in house testing laboratory verifies compliance for every batch. The team holds more than 15 years of direct food manufacturing experience.

All engineering staff hold full working knowledge of FDA requirements. Rapid prototyping services support fast new product development. They also provide full technical support throughout the entire production lifecycle. All products come with a full quality guarantee and required certifications.

• All tooling is manufactured entirely on site


• No third party contractors are used for production


• Batch traceability is maintained for every single part


• Modifications to existing tooling can be completed quickly 

Most suppliers provide only standard mold designs. They can provide high quality custom rubber seals. Additional parts including custom rubber seals can be supplied for all tooling. All products meet the same strict food safety and performance standards. 

Cleaning Methods to Preserve Mold Integrity

Proper cleaning and storage extend the working life of mold tooling. Most premature mold failure occurs as a result of incorrect cleaning practices. 

Daily Cleaning

Mild soap and warm water are sufficient for all routine daily cleaning. Rinse all surfaces completely immediately after use to remove residue. Do not allow food residue to dry fully onto the mold surface.

 Abrasive Materials

Never use abrasive scrubbers or steel wool on any silicone surface. These materials create tiny micro scratches that trap food and bacteria. Damage from abrasive materials is permanent and cannot be repaired.

 Deep Sanitisation

A weak vinegar solution is the best option for periodic deep sanitisation. This method removes all hidden residue without damaging the mold material. It also neutralises any odours that may develop.

 Stubborn Residue

A soft baking soda paste will remove almost all stubborn burnt-on residue. Apply the paste and leave for thirty minutes before gently rubbing. Rinse completely with warm water after treatment.

 Drying Procedure

Always allow molds to air dry completely before any long-term storage. Do not leave molds in direct sunlight during the drying process. Trapped moisture will cause permanent damage over an extended time.

 Storage Practice

Always store molds completely flat to prevent any permanent warping. Stack molds evenly and do not place heavy items on top of them. Store molds in a cool dark location when not in active use.

 Periodic Maintenance

Complete a full deep clean of all tooling once every three months. Inspect all surfaces for any signs of damage or micro cracking. Replace any tooling that shows signs of permanent degradation.

 Conclusion

Consumer safety remains the most important priority for all food production. The independent third party certification ensures full ongoing regulatory compliance. Platinum cure base materials offer reliable and superior long term performance.

Many manufacturers underestimate the long term cost savings of quality tooling. Rubber Silicone Molds delivers fully certified solutions for every production need. Their custom tooling designs match exact individual requirements. The right choice of mold material reduces risk and lowers operating cost.
