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:

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.

Quality control process

Learn the most stringent inspection methods we applies over the course of the entire manufacturing process.

Pre-production

Technical assessment

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.

Material verification

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.

In production

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.

Packaging

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

RD decor
cmm machine

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.

Quality reports

For every order on our platform, we can provide a full list of quality reports according to customers’ request. Including but not limited to:

  • Inspection report
  • Full dimensional report
  • Material test report

Certifications

As a decade-experience on-demand manufacturing company, we provide most commonly needed certifications, including but not limited to:

  • ISO 9001:2015
  • ROHS
  • REACH

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:

contact support@rapiddirect.com

  • 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.
