Functional prototypes
Evaluate geometry, assembly and performance in production-relevant metal or plastic.
CNC Machining Service
CNC machining services for prototypes and low-volume parts.
Cemal combines 3-axis, 4-axis and 5-axis machining with CNC turning, inspection and manufacturing support for global buyers.
Flexible machining
Use CNC where geometry, tolerance and material matter.
Machining can support early design work, finished components, mold construction and lower-volume demand.
Cemal machines metals and engineering plastics for prototypes, jigs, fixtures, mold bases, inserts, electrodes and customer parts. Multi-axis capability helps reduce setups on complex geometry, while turning supports round components and features.
For an accurate review, drawings should identify material, critical dimensions, surface finish, threads, tolerances, inspection expectations and quantity. If a material or finish is not yet fixed, explain the part's application so the engineering team can discuss manufacturable options.
Applications
Machining across the product and tooling lifecycle.
Mold components
Machine bases, cavities, cores, inserts and electrodes as part of the in-house tooling workflow.
Fixtures & jigs
Create manufacturing, inspection and assembly aids around the part and process requirements.
Low-volume parts
Produce smaller batches where machining is more practical than dedicated tooling.
RFQ checklist
Define what is critical and what is flexible.
| Geometry | 3D CAD plus a controlled 2D drawing for dimensions, threads, tolerances and notes. |
|---|---|
| Material | Specify grade and condition where required; otherwise describe the application and key properties. |
| Finish | Identify cosmetic surfaces, roughness, deburring, blasting, coating, anodizing or plating needs. |
| Inspection | Mark critical-to-function dimensions and the reporting or sampling level expected. |
| Quantity | Include prototype quantity and likely follow-on batches so the process can be planned efficiently. |
FAQ
CNC sourcing questions.
Can Cemal machine both metal and plastic?
Yes. The appropriate machine, workholding and cutting strategy depend on the material, geometry, tolerance and finish.
Can machining be combined with injection molding work?
Yes. CNC may support prototypes before tooling, mold components during tool construction, fixtures for inspection or assembly, and secondary work after molding.
What improves quote accuracy?
Provide native CAD, a dimensioned drawing, material, finish, quantity, critical tolerances, inspection needs and target timing.
Process selection
CNC machining or injection molding?
For metal parts, prototypes with changing geometry, and small batches without an injection mold, a CNC review starts with tool access, workholding and the drawing requirements. Deep pockets, thin walls and features reached from several directions need particular attention before a machining route can be confirmed.
For plastic parts intended for repeat production, compare the machining cost per batch with tooling, trials and the expected lifetime demand. A machined prototype can help assess fit, but does not establish how an injection-molded part will shrink, fill or look.
Explore low-volume injection molding when molded material behavior matters, or arrange an injection molding DFM review before committing to a mold.
What will be confirmed before production?
Use the agreed drawing revision to confirm material, achievable tolerances, finish, inspection scope, quantity and timing in the quotation. General machine capability is not a blanket tolerance or delivery guarantee for every geometry.
