DITAIDitaiPlastic was established in Dongguan in 2013; its founder entered the plastics industry in 1997. We make custom thermoformed housings, panels, covers and trays for OEM equipment. Tooling, sheet selection, forming, CNC trimming, surface finishing, hardware installation and assembly can be planned as one project rather than separate purchases.
Our largest CNC machining and trimming capability is 5000 × 2500 mm. That figure is not a guaranteed forming envelope: usable part size is checked against sheet grade, draw depth, geometry, tooling and trim access. Send the assembly and drawing for a project-specific review.

What we manufacture
Our work is custom, sheet-formed plastic components: machine and robot housings, vehicle covers, equipment panels, protective enclosures, display parts and reusable handling trays. A drawing may call for one formed shell or a delivered assembly with inserts, bonding, paint, graphics and fitted hardware. We agree the scope on the quotation so the buyer knows which operations and inspections are included.
Thermoforming is most useful when a large outer skin, lower tooling investment or design iteration matters more than fine molded detail on both sides. Injection molding may be a better choice for small, highly detailed parts at sufficiently high volume. We do not treat a formed cover as a structural or safety-rated component merely because the sheet has a published material rating.
Engineering questions before quoting
- Assembly datum: Which frame surfaces and holes locate the part? Share the mating structure and the order of installation, not only an isolated shell model.
- Wall distribution: Starting sheet thickness is not finished-wall thickness. Draw ratio, corners and local depth can thin the material; the critical zones need review on an actual formed sample.
- Trimmed features: Identify holes, slots, openings and cosmetic edges created after forming. Tolerances are agreed feature by feature, with datums and inspection methods on the drawing.
- Service conditions: Tell us about heat, sunlight, cleaning chemistry, impact exposure, fire requirements and expected service life. A resin-family name alone does not prove the finished part meets a specification.
- Handling and packaging: Large painted or high-gloss parts need defined support and contact points during assembly, packing and transport.
Capabilities and limits
| Process | Sheet thermoforming followed by CNC trimming and project-specific secondary operations. |
|---|---|
| Materials | ABS, PC, PETG, PMMA, HDPE, PP and other thermoforming grades are selected against the actual use conditions. Exact grade, colour, texture and documentation are agreed before approval. |
| Size | 5000 × 2500 mm refers to CNC machining and trimming capability. Formed-part feasibility is confirmed after engineering review. |
| Wall and tolerances | Starting gauge, minimum finished wall, datums, trim tolerances and inspection method are specified for each part. We do not apply a single tolerance to every geometry. |
| Tooling | Prototype and production tooling are selected for part geometry, finish, expected quantity and change risk. |
| Secondary work | Bonding, hardware and insert installation, sanding, painting, screen printing and mechanical or electronic sub-assembly can be included in the project scope. |
| Quality documents | Review certificate records, dates and scope and agree the inspection package required by your programme. |
How we develop a part
We begin with the drawing, the mating assembly and the intended use. The first review separates formed surfaces from trimmed features and identifies likely thinning, draft, undercuts, support points and access for CNC cutting. That gives both teams a useful decision: change the part, change the tool approach, or test a sample before freezing the design.
The first fitted sample is checked on the real frame wherever possible. For a visible seam, a dimension measured on a free-standing shell does not explain the final gap; brackets, fixtures, fastening sequence and adjacent panels also contribute. Revisions are recorded against the drawing so the production tool, trim programme and inspection plan refer to the same approved geometry.
Tooling, first-sample and production lead times depend on the geometry, material, finishing and acceptance requirements. We quote those milestones after review rather than promising a universal schedule.
What determines cost
Useful quotations separate the one-time tool from unit manufacturing. Tool material and complexity, sheet utilisation, local wall demands, CNC cycle time, finish, assembly labour, inspection and packaging all affect the total. A material substitution or revised bracket can change the economics even if the outside silhouette stays the same. We provide project-specific pricing after the drawing, quantity and acceptance criteria are clear.
Examples of project work
These published studies show the questions that changed the work, rather than claiming every project follows one standard route:
- Steering-column covers — assembly fit and the interfaces beneath the visible exterior.
- Automotive turnover trays — part location, handling and repeated use.
- Motorcycle air-intake panels — working with the customer through design and sample decisions.
What to send for an RFQ
A STEP model or dimensioned drawing is useful, but an initial enquiry does not need to be complete. Tell us what the part does, where it mounts, its approximate size, quantity, visible surfaces, service environment and target delivery date. Photos of the assembly or a marked-up existing part can reveal constraints the CAD model misses. If a fire, electrical, biocompatibility or other regulated requirement applies, name the exact standard and acceptance method; it must be reviewed at the material and finished-assembly level.
Our response should identify missing information, forming and trimming concerns, proposed material or tool options, and what will be verified on the first sample. Formal price and timing follow an agreed scope.
