Alibaba Supplier vs Direct Factory for Silicone Mold RFQs

Alibaba, email and WhatsApp are communication channels. They do not prove whether the counterparty is a factory, trading company or sourcing intermediary.

For a custom silicone project, the useful question is who controls DFM, tooling/master development, sample revisions, production, documents and the reorder record.

Verify the supplier before comparing only unit price.

A factory can sell through Alibaba.

A trading company can also provide good service.

The platform itself does not answer:

• who owns the process knowledge
• who makes tooling
• who approves samples
• who controls production
• who stores project records

Ask for:

• legal company name
• business license
• matching quotation/invoice entity
• payment entity
• factory/workshop address
• contact information

If the entities differ, ask for an explanation before payment.

Ask technical questions that require manufacturing knowledge:

• one-piece vs split?
• undercut strategy?
• master/tooling route?
• HCR/HTV vs LSR vs RTV?
• prototype validation?
• food-contact material/report scope?
• cavity-volume/weight control?

A seller who can only repeat a unit price may not control the engineering.

Useful evidence:

• real workshop photos/video
• tooling/process photos
• sample/prototype process
• QC evidence
• business license
• material/test documentation where applicable

Do not rely on stock factory photos.

Before paying, confirm:

• what the first payment covers
• CAD/modeling scope
• prototype/tooling scope
• revision approval
• production MOQ
• packing/shipping
• ownership/release terms if important

Can I sign an NDA before I send the full file?

Yes. For sensitive products, confidentiality can be handled before complete CAD/artwork is shared.

NDA does not automatically define tooling/CAD ownership. Address those separately.

A trading company may add value when it provides:

• multi-supplier consolidation
• procurement support
• local-language coordination
• mixed-category sourcing
• additional QC/logistics services

The key is transparency about who manufactures the project.

Compare suppliers on:

• legal identity
• DFM capability
• prototype plan
• process control
• document scope
• production lead time
• MOQ
• tooling/CAD terms
• shipping term
• reorder record

Is Alibaba less safe than WhatsApp?

The communication channel is not the main risk. Verify the counterparty and commercial terms.

Is a direct factory always cheaper?

No. Total cost depends on tooling, design, quality, service and logistics.

Should I send the same RFQ to several suppliers?

Yes. Use the same technical brief so the comparison is meaningful.

Send the RFQ you are using to compare suppliers. We can identify the missing technical inputs.
