How to choose a suitable oil seal manufacturer for customized cooperation?

Production capacity: Understand whether the manufacturer's production equipment is advanced and complete, such as whether it has high-precision rubber mixing equipment, automated oil seal molding machines, advanced skeleton processing equipment, etc. At the same time, examine its annual production capacity and whether it can meet its own order quantity and delivery requirements.
Technical R&D strength: Check whether the manufacturer has a professional R&D team and whether the R&D personnel have rich professional background and experience. You can also find out whether the manufacturer has independently developed new technologies and new products, and whether it can carry out customized R&D according to the special needs of customers.
Quality control system: Confirm whether the manufacturer has passed ISO9001 quality management system certification and other related quality certifications. Understand its specific quality control measures in raw material inspection, production process monitoring, finished product testing, etc., such as whether it uses advanced testing equipment to strictly test the dimensional accuracy, sealing performance, physical properties, etc. of oil seals.

Product performance: Inspect the various performance indicators of the manufacturer's existing oil seal products, such as pressure resistance, temperature resistance, wear resistance, sealing performance, etc., to see whether they meet industry standards and their own use requirements. The manufacturer can be asked to provide product performance test reports or test data for verification.
Product stability: To understand the quality stability of the manufacturer's products, you can check the evaluation and usage feedback of its past customers, or consult other companies in the same industry that have used the manufacturer's oil seals to understand whether there are frequent quality problems or after-sales problems.

Customization capability: Ask the manufacturer whether it can be customized according to your special needs, including size specifications, material selection, structural design and other aspects. For example, whether it is possible to customize oil seals of non-standard sizes, and whether special materials can be provided to meet special working conditions.
After-sales service: Understand whether the manufacturer's after-sales service system is complete, including whether it provides installation guidance, usage training, quality assurance period, after-sales repair or replacement services. Good after-sales service can solve problems encountered during use in a timely manner and reduce losses.

Cost composition: Communicate with manufacturers to understand the cost composition of their product prices, including raw material costs, production costs, R&D costs, management costs, etc. Make it clear whether the price includes other costs such as transportation costs and packaging costs to avoid cost disputes in the future.
Cost-effectiveness: Consider factors such as product quality, performance, and customization capabilities, compare prices of different manufacturers, and choose the manufacturer with the highest cost-effectiveness. Don't choose just because the price is low, but ensure that cost-effectiveness is maximized while meeting quality and usage requirements.

Customer evaluation: Collect other customers' evaluation and feedback on the manufacturer through online search, industry forums, social media and other channels to understand its performance in terms of delivery time, product quality, after-sales service, etc.
Industry reputation: Learn about the manufacturer's credibility from industry associations, partners, suppliers, etc., whether there is a bad record such as breach of contract, quality disputes, etc., as well as its overall reputation and status in the industry.
