Your Sourcing Risk Starts Not Only with the Machine but with the Contract Details

Many buyers spend much time negotiating machine price and specifications. But they often ignore delivery responsibilities, acceptance criteria, and after-sales terms. A high-quality machine may still cause project delays, cost overruns, or legal disputes if the contract fails to clarify shipping damage responsibility, installation timeline, or spare parts supply. Therefore, evaluating a Manufacturer requires looking at both factory strength and contract fairness.

A reliable injection molding machine purchase contract must clearly define delivery terms, acceptance standards, payment schedules, warranty scope, and penalty clauses. Haichen provides bilingual contracts in Chinese and English. All terms follow international trade practices. This ensures equal rights and obligations for both parties and removes uncertainty from the cooperation.

Below, based on 20 years of export contract negotiation experience, we reveal the 5 clauses in Injection Molding Machine Contracts and provide specific negotiation advice to help you complete your purchase safely and efficiently.

1. Define Acceptance Standards and Final Inspection Terms

The contract must clearly state the machine’s acceptance standards. These standards usually follow the jointly confirmed technical specification sheet. But the contract must also specify the test method (e.g., ISO standards) and the acceptance location.

Contract Item	What Buyers Should Ask
Screw size	Normally, the manufacturer will have 3 sizes of screw: A, B, C
Core puller	Does the machine include a core puller valve? How many sets?
Air valve	How many sets of air valves are included?
Acceptance standards	Do they follow the confirmed technical spec sheet?
Test methods	Does the contract specify ISO or other international standards?
Acceptance location	Is factory acceptance acceptable?

• Negotiation tip: Aim for factory acceptance testing (FAT) as the primary approach. In this arrangement, you or a third-party inspector visits the Manufacturer’s workshop to inspect the machine after assembly and testing. This prevents disputes caused by unclear responsibility when the machine arrives at your port but your factory is not ready for installation.

• Haichen’s practice: Haichen conducts strict FAT before shipment and provides complete test reports. We welcome customers to participate in factory inspections. All test data remains traceable. If you cannot visit in person, Haichen can arrange video acceptance. We install your specified mold on the machine and run actual production. We then evaluate the produced parts for dimensions and appearance to confirm the injection molding machine can run well with your molds. 

2. Define Shipping Responsibility and Risk Transfer Point

In international trade, shipping carries significant risks. The contract’s delivery terms play a critical role here.

Contract Item	What Buyers Should Ask
Delivery terms	FOB, CIF, or other Incoterms?
Risk transfer	At which point does risk transfer from seller to buyer?
Packaging standards	Does the Manufacturer provide professional export packaging?
Machine loading	It is hard to load the machine and fix it inside the container. It is better to make sure the way of loading.
Documents	Some countries need certification for the machine import.

• Negotiation tip: Prefer FOB (Ningbo Port) or CIF terms and clearly define the risk transfer point. Confirm whether the Manufacturer provides professional export packaging that protects against rust, moisture, and shock. Large injection molding machines without proper disassembly and wooden crating face high damage risks during long sea voyages.

• Haichen’s practice: Haichen uses fumigation-free wood for all export machines. We design large machines with quick-connect features for mechanical parts, electrical circuits, and oil pipes to ensure safe transport. We take photos before packing and share them with customers for confirmation.

3. Lock in After-Sales Response Time and Spare Parts Support

After-sales service is often the most vaguely defined part of a contract.

• Negotiation tip: Do not accept vague terms like “lifetime service.” The contract should clearly state: warranty start date (typically after arrival and installation), failure response time (e.g., within 48 hours), and spare parts pricing and delivery time for key components like screws, barrels, and hydraulic valves. A reliable Supplier should offer at least 3-5 years of spare parts supply commitment.

• Haichen’s practice: Haichen provides a guarantee list for all of the parts on our injection molding machine. Haichen also provides 24-hour online response service. When customers encounter issues, our engineers conduct real-time diagnosis and guidance via remote video. This solves most problems quickly. If on-site support is needed, we arrange dispatch immediately. All spare parts prices are locked in the contract to avoid future price increases.

4. Review Payment Schedule and Performance Bond

The payment structure is your last line of defense against risk.

• Negotiation tip: Avoid extreme payment methods like “100% before shipment” or “100% letter of credit.” Consider phased payments such as: 30% deposit + 40% before shipment + 30% upon arrival . You may also request a bank performance bond from the Manufacturer to hedge against delayed delivery or quality non-conformance.

• Haichen’s practice: Haichen supports flexible payment plans that follow international norms. We can also provide bank performance bonds or quality bonds upon request. We start production immediately after receiving the deposit and report production progress to customers at agreed milestones. Different countries will have different policies about the import payment. 

5. Define Technical Training and Documentation Scope

The machine is only hardware. Ensuring your team can operate it is equally important.

• Negotiation tip: The contract must specify the number of trainees, training days, and include on-site training during installation and commissioning. It must also list the full set of technical documents: electrical diagrams, hydraulic schematics, operation manuals (in Chinese and English), and spare parts catalogs. Machines without complete documentation make future maintenance extremely difficult.

• Haichen’s practice: Haichen provides a complete bilingual technical documentation package for each machine. More importantly, the machine’s computer control system offers 21 language options. Operators can perform all settings in their local language without translation. This significantly reduces training costs and the risk of operational errors. We also provide on-site training to ensure your team can handle daily operations and basic maintenance independently.

Choose the Right Manufacturer Starting with Contract Review

A well-drafted contract forms the foundation of long-term cooperation. It protects your investment and filters out unprofessional traders. As a reliable injection molding machine Manufacturer, Haichen maintains transparent contracts with clear commitments for every item.
