With decades of serving experience in tyre mould manufacturing field, we not only manufacture stable premium tire molds making silicone rubber, but also have accumulated a couple of strengthened factory suppliers of PU tooling boards, crucibles, aluminium beryllium alloy rods, casting plaster, foundry plaster etc. Strong supply ability, on-time delivery, reasonable price, good aftersales service and strong technical supports make us BBN Materials become trusted long-term partners of the tyre moulds manufacturers / tire molds factories. We strive to become your one-stop supplier of tyre mould patterning materials.
This video will show details of mold making procedures for tire mold master model. We do not insert stainless steel plates into the tire mold master model. It's just to show how the silicone mold is made for those who are interested in tire mold making and silicone rubber mold making. The silicone used in the video is A810 silicone rubber (12 shore A, 1:1 ratio). A810 silicone is a kind of pourable silicone with very low viscosity and high flowability which will capture every detail very well.

BBN A8 series tire molds patterning rubber are a kind of platinum-cured silicone rubber which are one of the premium tyre moulds curing / tire mold patterning materials. It has excellent tension and tear strength and flexibility, especially high fluidity and almost nil shrinkage. This kind of tyre moulds patterning / tire molds patterning silicone rubber is applied to the production of casting tyre moulds / tire molds and always can help you make perfect tyre moulds / tire molds.
10 and 20 shore A are the most widely used hardness for tyre moulds curing / tire molds curing, but it also should be in accordance with your own using habbits. Color and working time are adjustable as per your requirements.
BBN C8 series tire molds patterning rubber is a kind of tin-cured RTV silicone rubber which is one of the most widely used tyre moulds curing / tire mold patterning materials. It is great for tyre moulds / tire molds manufacturers especially who has encountered the semi-cured, sticking, or demoulding issues. It has excellent tension and tear strength and flexibility, and low shrinkage rate. This kind of tyre moulds patterning / tire molds patterning silicone rubber is applied to the production of casting tyre moulds / tire molds and always can help you make perfect tyre moulds / tire molds.
10 and 20 shore A are the most popular hardness for tyre moulds curing / tire molds curing. Some factories also use 40 shore A hardness. The hardness should be in accordance with your own using habbits. Color and working time are adjustable as per your requirements.

Polyurethane tooling boards are also called PU tooling boards, PU modelling & tooling boards, PU styling & modeling boards, CNC tooling boards, CNC modeling boards or CNC machinable boards which is one of the important tire mold patterning materials. It is ideally to make master models for tyre moulds / tire molds. BBN460 PU tooling board is specially designed for tyre curing moulds / tire curing molds field with blew features:
● Light brown / off-white color
● Density: 0.782g/cm ³
● Hardness: 68 shore D
● Good compressive strength
● Easy machinability, protect your CNC machine blades well
● Perfect smooth surface effect without jags or damage
We offer BBN460 PU tooling boards with below dimensions:
750*500*35/50/75/100mm
1500*500*50/75/100mm

Silicone carbide crucible is one of the tyre mould curing / tire mold patterning materials. It is used to melt alluminium alloys. Dimensions of our crucibles are similiar to Morgan crucibles. If you're using Morgan crucibles, then you can find the same dimension from us with cheaper price. Send us the drawing and quotation will be soon offered.
We offer silicone carbide crucibles with below dimensions:
Height range: 500~1300mm
Out diameter: 530~1170mm
Bottom diameter: 320~620mm

Aluminium beryllium master alloys are one of the main tyre mould patterning / tire mold patterning materials. It is perfect for anti-corrosion which makes your tyre moulds / tire molds longer service life.
We offer master alloys Al 1% Be / Al 2.5% Be / Al 5% Be.
Shapes could be rod or wire.
Regulation: 100g/rod, 9.5mm diameter, 5kg/tie, 500kg/pail
500kg/wire, 9.5mm diameter.

Plaster is one of the indispensable tyre mould patterning / tire mold patterning materials. We offer cover plaster, back plaster, channel plaster, and casting plaster / foundry plaster for tyre moulds patterning / tire molds making and other precision casting applications.
Channel plaster (OHZ-3) is for setting a runner for the aluminum solution to flow into the mold cavity.
Cover plaster (OHZ-10) is usually used on the top. It is for isolating the molds and the air. Cover plaster can also be used as channel plaster.
Casting plaster (OHZ-6) is also called foundry plaster which is mainly used for casting plaster cores.
Back plaster (OHZ-B) is mainly made as a base for silicone molds to prevent the silicone molds from deformation.
