We can maintain strict tolerances in difficult to process polystyrene materials. Our CNC machining services utilize modern CAM systems and state-of-the-art machining and measurement equipment to ensure the highest quality products and customer satisfaction.

Why Is CNC Machining Better Than Injection Molding for Manufacturing Non-standard Polystyrene Parts?

  1. Compared to injection molding, CNC machining can produce prototypes within a few hours.
  2. CNC produced parts are more precise than injection molding. The computer control and automation in CNC machining allow for the creation of precise polystyrene parts.
  3. CNC processing of polystyrene can achieve better surface smoothness. In contrast, due to the melting and strong pressure inside the mold, injection molding can result in a slightly rough surface finish.
  4. CNC machining can create complex geometric shapes. And retain all physical and mechanical properties of the thermoplastic.
  5. CNC machining is more suitable for small batch manufacturing.

The Main Types of Polystyrene Plastics

Ordinary PolystyreneOrdinary polystyrene resin is a non-toxic, odorless, and colorless transparent particle, resembling a glass like brittle material. Its products have extremely high transparency, a light transmittance of over 90%, good electrical insulation performance, easy coloring, good processing fluidity, good rigidity, and good chemical corrosion resistance.
Expanded PolystyreneExpanded polystyrene has the advantages of low relative density (1.05g/cm3), low thermal conductivity, low water absorption, impact and vibration resistance, thermal insulation, sound insulation, moisture-proof, vibration reduction, and excellent dielectric properties. It is widely used as an shock-absorbing packaging material for mechanical equipment, instruments, household appliances, handicrafts, and other easily damaged and valuable products, as well as for the packaging of fast food.
High Impact PolystyreneHigh impact polystyrene is a thermoplastic material made from elastomer modified polystyrene. The two-phase system composed of rubber phase and continuous polystyrene phase has developed into an important polymer commodity in the world. This universal product has a wide range of impact and processing properties, making it widely used in automotive, machinery, electric products, furniture, household appliances, telecommunications, electronics, computers, disposable goods, medicine, packaging, and entertainment markets.
Syndiotactic PolystyreneAlthough the emergence of syndiotactic polystyrene was more than half a century later than general polystyrene, syndiotactic polystyrene not only inherits the excellent characteristics of general polystyrene, such as low density, excellent electrical properties, good hydrolysis stability, and low cost; Moreover, syndiotactic polystyrene belongs to the semi crystalline polymer, which has excellent mechanical properties, heat resistance, solvent resistance, and dimensional stability due to crystallization. Its crystallization rate is much faster than that of syndiotactic polystyrene, allowing for molding processing. Therefore, syndiotactic polystyrene is widely used as a new type of engineering plastic.
