RapidDirect manufacturing standards
Tighter tolerance are examined on a case by case basis with your technical drawings. Contact with email@example.com for special requirements.
RapidDirect, provides high tolerance CNC machining processes including 3, 4, 5 axis CNC milling, CNC turning, and post-processing services for your diverse manufacturing requirements.
|Linear dimension||+/- 0.025 mm|
+/- 0.001 inch
|+/- 0.025 mm|
+/- 0.001 inch
|Shaft diameters||+/- 0.025 mm|
+/- 0.001 inch
|Smallest thread size available||M1x0,25|
|Part size limit||950 * 550 * 480 mm|
37.0 * 21.5 * 18.5 inch
If no 2D drawing is provided, RapidDirect produces parts according to ISO 2768 M standard. With 2D drawing, we can reach tolerance as tight as +/- 0.01 mm.
At RapidDirect, we offer various injection molding services which includes rapid tooling, family molds, multi-cavity molds, over molding, etc., for your manufacturing needs. Each service is based on various manufacturing standards highlighted below:
|Part size (mm)||Production tooling||Rapid tooling|
We have experience and the right sheet metal fabrication services necessary to bring that YOUR idea to life. This includes services like high tolerance and wide thickness range laser cutting, bending capabilities, and other post-processing options.
|Edge to edge, single surface||+/- 0.005 inch|
|Edge to hole, single surface||+/- 0.005 inch|
|Hole to hole, single surface||+/- 0.005 inch|
|Bend to edge / hole, single surface||+/- 0.010 inch|
|Edge to feature, multiple surface||+/- 0.030 inch|
|Over formed part, multiple surface||+/- 0.030 inch|
|Bend angle||+/- 1°|
By default, sharp edges will be broken and deburred. For any critical edges that must be left sharp, please note and specify in your drawing.
3D Printing is the best service if you want the best functional parts prototyping. At RapidDirect, we provide you with the best technologies in 3D printing such as FDM, SLA, SLS, Polyjet. For other technologies associated kindly contact us.
|Process||Min. wall thickness||Layer height||Max. build size||Tolerance|
|SLA||1.0 mm||50 – 100 μm||250 * 250 * 250 mm||± 0.5% with a lower limit of ± 0.5 mm (± 0.020″)|
|SLS||1.0 mm||100 μm||420 * 500 * 420 mm||± 0.5% with a lower limit of ± 0.15 mm (± 0.006″)|
|FDM||1.0 mm||100 – 300 μm||500 * 500 * 500 mm||± 0.3% with a lower limit of ± 0.3 mm (± 0.012″)|
Quality control process
Learn the most stringent inspection methods we applies over the course of the entire manufacturing process.
Before the production stage begins, our engineering team performs a technical assessment on your parts design. This includes an assessment on important factors such as material, surface finish, structure, process, and other details of your 3D and 2D drawings.
On our customer’s request, we provide a certification of the material we used for making your parts. The report comes from the raw material manufacturer and usually includes: material heat number, material grade, material dimensions, mechanical properties, chemical analysis, etc.
On-site inspection system
In precision machining, it is important that materials being worked on is always at the right position. With on-site inspection system, positions are examined automatically, and adjustments are made accordingly. Using on-site inspection system further helps avoids issues at the early stage, saving cost and time.
In-process quality control
At RapidDirect, we strictly obey the ISO9001:2015 requirements. The quality control staff conducts routine inspections for all parts that are being produced every 2 hours. This further prevents risks from happening.
Before delivery inspection
Full-dimensional inspection report
For all orders, we provide full dimensional inspection report on request. This report will include the following: quantity of parts, critical dimensions, threads and tolerances, thicknesses and depths, part appearance, etc.
Ensuring that the parts we manufacture are of the highest quality is important. We know about the unpredictability of logistics. Therefore, we make sure we lower the risk to the parts during our packaging process. Four layers of protection: 1. wrapping paper 2. EPE 3. foam 4. paper/wooden box are applied during the packaging process, ensuring that we deliver the most high-quality and beautiful parts to you.
In-house inspection equipment
We use the Coordinate Measuring Machine (CMM) for dimensional inspection of parts produced. CMMs can measure physical parts of an object by sensing and collecting points along its surface using a probe. It is especially suitable for parts with complex geometries.
On completing the manufacturing process, we use optical comparator/ a projector to inspect the dimension of the components. This projector is ideal for dimensional check as it precisely measures the part’s dimensions and compare them to the original CAD model. Any inconsistencies detected by the projector are alerted in a detailed inspection report.
We employ X-Ray Fluorescence (XRF) analysis for checking the material quality. The XRF analyzer uses short X-rays and gamma rays to determine the elemental composition of metals, plastics and other materials, to inspect the quality of the materials.
First article inspection
For low-volume injection molding and CNC machining orders exceed 50 units or 5000 USD in total price, first article inspection is available on request. The process goes like below:
- The customer request first article inspection for a project that meets our FAI requirements.
- RapidDirect reviews on the project and contacts customer for detail information.
- The customer signs the FAI agreement provided by RapidDirect and agree on our Terms and Conditions.
- RapidDirect produce sample parts according to FAI agreement and deliver to the customer.
- The customer receives and examines the parts, inform RapidDirect if full-scale production may begin.
- The full-scale production starts and finishes production within lead time.
