FAQ

  • Q What type of surface finishes does Jucheng Precision provide?

    A
    We offer a wide variety of finishing services to achieve almost any look and feel on your parts. We offer treatments for metal, texturing for plastic injection mold tools, painting for metal and plastic, and many more. 
     
  • Q What tolerances can Jucheng preicision achieve?

    A
    There is not a given set of tolerances that fits all processes and materials. In every case, the final tolerances on your part will depend on a number of factors, including but not limited to:
     
    1. Part size / Design geometry/  The number, type and size of features
     
    2. Material(s) / Surface finish /  Manufacturing process
     
    3. Once your order is confirmed, we will review your design and provide a design for manufacturing review, pointing out any areas where we may not be able to achieve your desired tolerances. It’s helpful if you can specify which areas in your design have critical tolerances that must be met and which can be slightly modified if needed to reduce time and costs involved. Here are some general tolerance guidelines:
     
    4. General tolerances for CNC machining in metal and plastic
     
    5. Plastic injection molding tolerances
     
    6. General tolerance for metal 3D printing is +/- 0.5mm
     
    7. Shrinkage rate of +/- 0.15% is to be expected for vacuum casting
     
    8. All manufacturing and technical specifications need to be clearly specified in the 2D drawings in order to be followed.
     
  • Q When should I use machining versus injection molding?

    A 1. Before making the investment to have injection-mold tooling made or high-volume machining processes, you likely will want to test a part that is as close to the production part as possible. CNC machining is the best option for this situation.

    2. Additionally, engineers often need just one or maybe a few parts for test fixtures, assembly jigs, or assembly fixtures. Machining is the best option here as well, but traditional machine shops often charge a significant non-recurring engineering (NRE) charge for programming and fixturing. This NRE charge often makes getting very small quantities not affordable. The automated CNC machining process eliminates the upfront NRE costs and is able to offer quantities as low as one part at an affordable price and get parts in your hands in as fast as 1 day.

    3. Injection molding is better suited to support larger amounts of samples for functional or market testing, bridge tooling, or low-volume production. If you need parts before a steel tool can be made (typically 6 to 10 weeks with other molders) or your volume requirements don't justify expensive steel production tooling, we can supply production parts to meet your full requirements (up to 10,000+ parts) in 1 to 15 days.
  • Q When should I choose Vacuum Casting Services?

    A
    Vacuum casting is a method for making high quality prototypes or low volumes of parts formed from inexpensive silicone molds. Copies made in this way show great surface detail and fidelity to the original pattern.
     
  • Q When should I choose 3D printing Services?

    A
    1. We can use diverse 3D printing processes to fabricate your parts. More rapid and cost-effective compared with CNC Machining from one piece to large quantities.
     
    2. 3D printing has become a standard technique for developing one-off visual prototypes due to its speed, affordability, and flexibility. Printed parts sometimes lack strength and impact resistance, but this matters little for visual prototypes.
     
  • Q When should I choose CNC Machining Services?

    A
    1. 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.
     
    2. 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.
     
    3. 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 order just one piece?

    A
    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.
     
  • Q How long does the shipping time take?

    A
    1. Generally, for European countries 3-4 days, for North American countries 4-5 days, for Australia 3-4 days, for South American countries 5-7 days, for Midest Asia countries and North African Countries 5-7 days.
     
    2. But shipping time is unpredictable due to some emergency situations, it may be delayed like high-peak season, pandemic happening or other force majeure.
     
  • Q How quickly can I get my parts?

    A
    1. Quality parts can be made in as little as two weeks if you provide us with complete 2D and 3D CAD models. More complex parts requiring or other special features will take longer. Request a quote to get more accurate lead times based on your project.
    2. As for shipping, most of our shipments are via air freight, which can take a few days from China to Europe or North America.
     
  • Q Are lead times in working days or calendar days?

    A
    Lead times are quoted in calendar days. As per our Terms and Conditions, quoted lead times commence only after completion and confirmation of design for manufacturing review and the beginning of actual production.
     
  Rapid Prototyping & On-Demand Manufacturing In Days.
  ONE-STOP services from prototyping to batch production.
