China is home to thousands of injection molding companies producing molds for every application imaginable. But sourcing molds that consistently deliver top quality and performance requires careful vetting of China suppliers. This step-by-step guide covers how to identify and select the best “China injection molding” and “China mould” partner for your needs.

Overview of the 6 Steps

  1. Define injection mold requirements
  2. Research China mold manufacturers
  3. Send RFQs and evaluate quotes
  4. Visit top facilities and manufacturers
  5. Validate with a test order
  6. Place full order and manage project

Follow these steps to ensure you get precision molds engineered to your specifications at the best value. Let’s look at each step in more detail.

Step 1: Define Injection Mold Requirements

First, detail your mold specifications so manufacturers can properly quote and deliver the right solution:

  • Plastic material type
  • Shot size and clamp force needs
  • Part dimensions, tolerances and cosmetic requirements
  • Annual volume and target cycle times
  • Cavity count and layout
  • Cooling and ejection requirements
  • Special design features like side actions

Being precise upfront prevents misaligned expectations.

Step 2: Research China Mold Manufacturers

Next, research and shortlist China injection molding companies that specialize in your type of mold.Exploring Plastic Fabrication Expertise in China. Good resources include:

  • Trade directories like
  • Industry events like Chinaplas trade show
  • Importer forums for reviews and referrals
  • Your existing network of suppliers

Look for specializations, experience, quality certifications, clientele, and expertise relevant to your project. Narrow down to 4-6 of the most qualified matches.

Step 3: Send RFQs and Evaluate Quotes

Send RFQs to the shortlisted companies with complete mold specifications and requirements. Provide 3D models or drawings if possible.

Assess the detailed quotes on:

  • Cost competitiveness
  • Clarity in scoping inclusions/exclusions
  • Proposed timelines and project plans
  • Alignment with your requested terms
  • Design optimization recommendations
  • Responsiveness and attention to detail

Follow up with the top 2-3 contenders to address any open questions.

Step 4: Visit Top Facilities and Manufacturers

Schedule visits to the top prospect’s factories in China. On site, you can:

  • Inspect equipment, facilities, and quality control
  • Meet the team that would work on your molds
  • Review technical capabilities in person
  • Validate certifications and credentials
  • Assess responsiveness and communication
  • Request referrals from existing clients

This is a must for verifying capabilities and building trust.

Step 5: Validate with a Test Order

Before full production, have the chosen vendor make 1-2 samples molds for evaluation:

  • Check for design conformance to specs
  • Inspect molding performance – cycle times, quality, etc.
  • Review molded part samples – dimensions, cosmetics, etc.
  • Consider independent inspection for unbiased verification

This test order validates the mold quality and manufacturing process.

Step 6: Place Full Order and Manage Project

If satisfied with the samples, finalize pricing and payment terms and place the full mold order. Clearly define project plans, timelines, inspection processes, and procedures for design approvals.

Stay actively engaged throughout manufacturing to prevent delays. With diligent vetting and validation upfront, you can feel confident you’ll receive exceptional “China injection molding” and “China moulds” tailored to your needs.
