Tool steel is a type of high-carbon, high-alloy steel that is specifically designed to be used in the manufacture of cutting tools, dies, molds, and other types of tooling.
From CNC Prototyping To Low-volume Production
Protoryping
Prototyping is the process of creating a physical model of a product or part, typically using manufacturing techniques such as 3D printing. 
 
The purpose of prototyping is to test and refine the design, and to ensure that the product functions as intended. 
 
Prototyping can help to identify any design flaws or issues that may need to be addressed before moving into production.
Low-volume Manufacturing
Low-volume manufacturing is a rapid production method that precedes full-scale production, ranging from 100 to 100,000 units. 
Jucheng Prototypes is committed to providing high-quality custom parts that strictly meet your design requirements and specifications via vast low-volume manufacturing services, including CNC machining, rapid injection molding, vacuum casting, sheet metal,reaction injection molding, and more. 
Low volume manufacturing allows companies to test their designs and products before investing in large-scale manufacturing, reducing the risk of product failure and financial loss.

How we check your parts?
Parts Drawing Checking | Jucheng Precision
 
Drawings Checking

we will check every item on the BOM like quantity, material, process, and surface finish requirements, and see if they are in accordance with the quotation. Meanwhile, our engineering team will check 3D and 2D drawings to see if there are any design errors, in accordance, with interference, and confirm all the tolerance are okay to be machined.

Meanwhile, DFM will be sent when it is necessary.
Incoming Material Inspection | Jucheng Precision  
Incoming Material inspection

We asked our material supplier to provide certification and paste marks for all the materials. And we will check the materials with Spectrometer to test the material chemical components.
In Processing Checking | Jucheng Precision
 
In processing checking

In this stage, we will go both with visual checking and manual checking.

Our experienced and skillful craftsman will check the parts with 3D drawings. 

We understand that it is very essential to check the parts when machining and avoid time-wasting. If necessary, we can provide you with the first sample when it comes to batch production.
Final Inspection | Jucheng Precision  
Final Inspection

We have 6 well-trained engineers in our QA department.

We can provide inspection reports like 3D scanning reports, Cleanness reports,100% dimensional reports, PPAP, Control Plans, etc.

FAQs

    Q When should I use machining versus injection molding?

    A
    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.

    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.

  • Can Jucheng Precision provide optical quality on my plastic parts?

    Yes. We combine the machining capabilities of the best combined 3-axis, 4-axis or even 5-axis CNC milling machines. We also have adopted the latest diamond machining technology in ultra-precision manufacturing. This is a technique called Single Point Diamond Machining (SPDM or SPDT) that can match the ability of 5-axis micro-milling to produce a range of lens and light guides types of excellent optical quality in an array or freeform pattern. With the rich polishing experience, we can get amazing appearance on both inside and outside of the parts, providing fully support to clear and optical prototype development projects.
  • 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.
  • 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.
  • 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.
