CNC Machining Material Selection

    At Jucheng Precision, More than 28 engineering-grade materials can be used for CNC plastic machining. The machined plastic parts are 100% functional and able to be mechanically tested.
      Lead Time
      Standard Tolerance: ISO2768-Medium for plastic parts
      As fast as 2 days
      ABS – (Natural / Black / Flame Retardant)
      PVC- (Black/white)
      PC / Polycarbonate – (Clear / Black)
      PMMA / Acrylic – (Clear / Black)
      PA / Nylon – (Natural / Black / 30%GF)
      HDPE- (Black/white)
      PP / Polypropylene – (Natural / Black / 20% GF)

    Clear and optical prototypes are usually made from transparent acrylic (PMMA) and polycarbonate (PC)., which is used like automotive lighting parts, home appliances, compressors, or parts displays, etc.

    Jucheng precision provides various technologies like CNC milling, vacuum casting, and injection molding, from quality 1 to 10000 PCS.

    At Jucheng precision, we make custom clear parts and optical components to meet your functional and aesthetic needs. Designers will benefit from the use of transparent parts to achieve optical functions, view the internal structure of parts or show the aesthetics of the parts. With our highly skilled polishing techniques, PMMA can achieve the best clarity and light transmittance by precision and hand polishing, while PC achieved its clarity and transmittance by vapour polishing. PC’s transparency is second only to PMMA, but its strength is much stronger than PMMA.
    At Jucheng Precision, we have combined 3-axis, 4-axis and 5-axis CNC milling, CNC turning and other manufacturing processes such as drilling, tapping, EDM, surface grinding to expand the manufacturing capabilities of the metal prototypes, and accommodate any challenge with ease, and save time and cost.

General Tolerances CNC Machining

Through a rigorous project management process, Shenzhen Jucheng Precision is able to ensure the cost-efficient, on-time delivery of every precision component manufactured, At our general tolerances for CNC machining of metals is DIN-2768-1-fine and for plastics, DIN-2768-1-medium. Tolerances are greatly affected by part geometry and type of material. Our project managers will note and consult with you on every details of your project and will seek to provide the highest degree of precision possible.

At Jucheng Precision, we will constantly follow the general tolerance for CNC machining. 

1. For Metal parts, we follow DIN-2768-1-fine 

2. For Plastic Parts, we follow DIN-2768-1-Medium

Low-Volume Manufacturing

Low-volume manufacturing is a rapid production method that precedes full-scale production, ranging from 100 to 100,000 units.

Jucheng is a low-volume manufacturer that applies unsurpassed level of expertise to deliver quality and repeatability on every part. We determine your best pathway to the marketplace based on your project’s goals and expectations, providing cost-effective and rationalized advice from designs, materials, production processes, manufacturability, etc.

  • Q When should I choose CNC Machining Services?

    Machined parts have the true properties of the material you select. Our process allows you to get parts machined from blocks of solid plastic and metal in the same time frame.

    We mill and turn low quantities of parts very quickly. Typical quantities are one to 200 pieces and manufacturing times are 1 to 3 business days. We offer product developers parts machined from engineering-grade materials that are suitable for functional testing or end-use applications.
    CNC machining is more expensive than plastic 3D printing, but it is the most feasible option for metal visual prototypes given the high cost of metal 3D printing and metal casting.
  • Q Can I get tight tolerances CNC parts from Jucheng Precision?

    Jucheng Precision is known as one of the best CNC machining companies in China in terms of quality, speed, and customer service. With high-quality CNC machines, we can easily achieve +/- 0.02mm of tolerance and can even get within +/- 0.01mm. But keep in mind that it can have an impact on the cost.
  • Q Can I order just one piece?

    Yes, of course you can, there is no minimum quantity at Jucheng Precision, we will recommend you with the most suitable and effective manufacturing solutions based on your quantities.
  Rapid Prototyping & On-Demand Manufacturing In Days.
  ONE-STOP services from prototyping to batch production.
