Question

Answer

What is the main difference from the laser-cutting cell?

This machine uses dedicated mechanical punch-and-die tooling. It is attractive for stable, repeated geometry, while laser cutting offers more programmable flexibility for changing variants.

Can the system punch painted bumpers?

Yes, when the coating, local support, clearance and any pre-conditioning step are validated with representative painted parts. Edge acceptance must be agreed before FAT.

Can one tool support several hole quantities?

A modular or changeable tool may support related variants, but the concept depends on hole location, access, available space and takt.

How are loose slugs controlled?

The cell can use a chute, collection bin, vacuum handling and/or slug detection according to the risk assessment.

What information is required for an application review?

Please send part 3D data and drawings, exact resin grades, joint or stake details, production-equivalent samples if available, CTQ and test requirements, takt, annual volume, variant mix, utilities and plant standards.

Can Dizo Sonics test our real parts before quotation?

Yes. An application review and representative-part trials are recommended when feasibility, tooling concept or cycle assumptions need evidence. Trial scope, sample quantity and test method are agreed before testing.

How is the final cycle time confirmed?

The committed cycle is based on trials and a complete sequence study including loading, clamping, joining, cooling, inspection, data handling and unloading. Published reference cycles are not universal guarantees.

Which plastic materials can be processed?

Suitability is approved at exact-grade level. Resin chemistry, fillers, moisture, additives, color, recycled content, molded-part variation and joint design can all change the process window.

What documents are supplied with the machine?

The project handover package can include the approved specification and layout, electrical and pneumatic documentation, manuals, maintenance plan, spare-parts list, parameter backup, inspection records and FAT documents according to the contract.

Do you support FAT, installation and SAT?

Yes. FAT and SAT activities are defined in the project plan. Installation, training and on-site support depend on destination, responsibility split and the commercial scope.
