CNC machining model and tire mold material In traditional plaster craftsmanship, models were usually made by hand using plaster. As the requirements for precision and appearance are getting higher and higher, more and more manufacturers have used their own model processing centers, and more and more processable plastics have replaced the original gypsum processing technology, and even directly use CNC to process tire molds. Due to industrial automation and labor costs, traditional manufacturing is facing increasing competitive pressure. We have developed a high-performance material for the rapid manufacture of models and tire molds - processable plastic sheets - Rich products, density 80-1700Kg/m3 - Good processing performance and less dust - Can be customized according to customer needs - Exclusive ingot or mold casting is also available -Complete service plan, can provide cutting, bonding and processing Machinable wood - obomodulan 302 Density 0.3, pink. Surface hardness 28-45 (Shore D) Heat distortion temperature 80 ℃. Machinable wood - obomodulan 502 Density 0.47, apricot. Surface hardness 40-50 (Shore D) Heat distortion temperature 95℃ Machinable wood - obomodulan 700 Density 0.7, reddish brown. Surface hardness 65-70 (Shore D) Heat distortion temperature 80℃ Machinable wood - obomodulan 1200 Density 0.77, brown. Surface hardness 80-85 (Shore D) Heat distortion temperature 90 ℃. Machinable wood - obomodulan 1600 Density 1.60, white. Surface hardness 85-90 (Shore D) Heat distortion temperature 94℃ Machinable wood - obomodulan 1600 Density 1.60, grey. Surface hardness 85-90 (Shore D) Heat distortion temperature 120℃
Resin master mold
traditional lamination process - Gypsum prototype surface treatment (sealing, waxing and polishing) - Surface gel coat SP404 or SP410 －Transition layer, epoxy system RL528+ quartz powder Or low viscosity epoxy system RL528+ glass fiber cloth - Lamination system, epoxy system RL528 + stone rice tamping - Reinforcing layer, epoxy system RL528+ glass fiber cloth Resin master mold structure process - The upper mold adopts a lightweight structure (gel coat + epoxy fiberglass or epoxy fiber paste LP130) - The lower mold is a heavy structure, mainly using gel coat SG404 + epoxy resin system RL528 + stone rice
Soft Molded Rubber - Use wax sheets or other materials of equal thickness to reserve the size of the soft glue - After the laminated resin structure has cured, remove the wax sheet - The elastic resin layer is poured by surface casting method. - Gray glue is easy to trim and sand - Yellow glue has a more wear-resistant surface and better bonding with the resin matrix
Scale cast tire mold resin system
The tire mold blank system is directly cast by the PU casting resin system of the order of magnitude, and the tire mold is directly processed by CNC after curing.
Porous plastic working mold outer mold and master mold material ①The hand lay-up molding process and structure are similar to the traditional plaster working mold master mold: Remake microporous resin mold surface + interface glue (RC906) + transition reinforcement layer (epoxy fiber paste LP130) + epoxy lamination system (epoxy mold system RL528 + stone rice or river sand) on transition mold or model The lamination adopts a light-filled epoxy resin system (SW325, density 0.65), which is suitable for automatic assembly lines, and the mold is light and energy-saving. Microporous resin cavity - porous resin M210R, with a pore size of 7-13 microns, good permeability and processability. Interface adhesive--CW256 or RC906 thixotropic resin system, thixotropic and easy to operate, used for waterproof sealing of molds, transition bonding between microporous resin cavity and epoxy system of backing material, curing in humid environment. ②Microporous resin surface casting or full casting process: The microporous resin is cast in the prepared mold cavity or mold frame, and after curing, CNC machining is performed. The processed mold cavity and mold frame and related connection control pipelines are installed or bonded with epoxy. (Interface glue + epoxy fiber paste) The microporous resin PCS-2 component material is selected, which is easy to operate. Longer gel time (5-6min)
