Frequently Asked Questions (FAQs)

How do I find reliable injection moulding manufacturers?
Start by searching online directories, trade platforms, and professional networks. Attend industry trade shows, ask for referrals, and check company websites for experience and certifications. Comparing reviews and case studies can also help identify reliable partners.

What factors should I consider when choosing a manufacturer?
Look at their experience, production capabilities, quality assurance processes, lead times, and pricing. Ask about minimum order quantities and whether they can handle your product specifications. Communication and customer support are also key factors.

How can I verify a manufacturer’s quality standards?
Request documentation of industry certifications such as ISO 9001 or similar standards. Ask for samples of their work, customer references, and inquire about their in-house quality control and testing procedures to ensure they meet your requirements.

Is it important to visit the factory before placing an order?
Visiting the factory helps you assess their facilities, equipment, and working conditions firsthand. While not strictly necessary, it builds trust and helps identify any potential issues early in the partnership. If you can’t visit, consider hiring a local inspection agent.

What should be included in a manufacturing agreement?
Ensure the agreement covers product specifications, pricing, payment terms, delivery schedules, quality standards, intellectual property protection, and procedures for handling defects or delays. Clear contracts help prevent misunderstandings and protect both parties.
