CNC machining models and tire mold materials



In traditional gypsum craftsmanship, models were usually handmade using gypsum. With the increasing demand for precision and appearance, more and more

The manufacturer has adopted its own model processing center, which can process more and more plastics instead of the original gypsum processing technology, and even

Directly machine the tire mold with CNC.

Due to industrial automation and labor costs, traditional manufacturing is facing increasing competitive pressure. We have developed a rapid manufacturing system



High performance materials for models and tire molds - processable plastic sheets

- Rich products with a density of 80-1700Kg/m3

- Excellent processing performance and minimal dust

- Customizable size according to customer needs

- Exclusive ingots or molds can also be provided for casting

- Complete service plan, providing cutting, bonding, and processing services

Resin master mold

Traditional lamination process

Surface treatment of gypsum prototype (sealing holes, waxing and polishing)

Surface adhesive coating SP404 or SP410

Transition layer, epoxy system RL528+quartz powder

Or low viscosity epoxy system RL528+glass fiber cloth

- Laminated system, epoxy system RL528+crushed stone

- Reinforcement layer, epoxy system RL528+glass fiber cloth

Resin master mold structure technology

- The upper mold adopts a lightweight structure (adhesive coating+epoxy fiberglass or epoxy fiber paste LP130)

- The lower mold is a heavy structure, mainly using adhesive coating SG404+epoxy resin system RL528+stone rice



Soft mold rubber

- Use wax sheets or other materials of equal thickness to reserve soft rubber dimensions

After the laminated resin structure is cured, remove the wax sheet

- Use surface casting method to pour elastic resin layer.

- Gray glue is easy to repair and polish

Yellow rubber has a more wear-resistant surface and better adhesion to the resin matrix



Scale casting tire mold resin system

The tire mold blank system is directly cast using a grade PU casting resin system, and after curing, the tire mold is directly CNC processed.



Porous plastic working mold

We provide porous resins/machinable sheets and porous molds for various application fields.

Our products create value for customers in industries such as thermoforming, vacuum forming, vacuum clamping, automotive, semiconductor, ceramics, etc.

Our porous tooling resin and board are composite materials composed of multiple components.

Our porous materials have stable and uniform pore distribution, ensuring high-quality parts that meet your requirements.

Different types of fillers and particle sizes, such as aluminum, stainless steel, ceramics, or mineral fillers, are used for various applications

Aperture, high mechanical strength, breathability, high temperature stability, and other characteristics are important parameters that need to be considered

The material can be treated with hydrophilic or hydrophobic properties to meet different application scenarios



Epoxy porous resin system (non-metallic material)

After the solidification of the liquid casting tooling resin system, there are different pore/aperture distributions on the surface and inside. The mold mainly uses the pore/aperture distribution formed on the solidified surface to meet our usage requirements. Therefore, the system cannot be CNC machined after solidification, and can be slightly polished on the surface. Suitable for small and medium-sized ceramic pressure grouting molds.

EC612- pore size 1-2um, porosity 40-60%; Hardness D50-60; 6 components+water

EC623- pore size 2-3um, porosity 40-60%; Hardness D50-60; 6 components+water

EC634- pore size of 3-4um, porosity of 40-60%; Hardness D50-60; 6 components+water

EC615- pore size 5-10um, porosity 40-60%; Hardness D50-60; 7 components+water


Acrylic acid porous resin system (non-metallic material)

Our acrylic microporous resin system has the same properties in terms of surface and internal pore size distribution after curing, so it can be pre cast and cured first, and then CNC machined to greatly improve the efficiency of mold manufacturing. (Surface casting or full casting)

Suitable for mass production of ceramic pressure grouting molds.

M611 has an average pore size of 5um and a porosity of 30%; Hardness D70, 4 components+water

M121 has an average pore size of 5-10um and a porosity of 30%; Hardness D70, 5 components+water

M128 average pore size 10-20um; porosity 30%; Hardness D70, 5 components+water

M125 average pore size 20-30um; porosity 30%; Hardness D70, 5 components+water



Porous machinable sheet metal system (filled with metal or non-metal materials)

More choices, more powerful features, and more application scenarios. Such as biomedical filtration, vacuum adsorption, semiconductor vacuum fixtures, air cushion transportation, EPS and EPP foam molds, exhaust of injection molding molds, heat dissipation and ventilation of battery packs or telecommunications products, pulp molding, and ceramic injection molding molds. It can absorb water autonomously or involuntarily to meet more usage process scenarios.

Good machinability and polishability, uniform distribution of pores/aperture, can achieve higher design requirements from customers. Due to the microporous nature of the board, drilling is no longer required. Its micro permeability replaces the molding/demolding exhaust holes required for traditional tools (molds used for deep drawing plastic films and sheets). The sheet can be easily bonded to large and deep drawn molds or connected to aluminum frames.
