Who is Deran: High standard factory focusing on OEM & ODM slipper manufacturing
Deran is a professional slipper manufacturer headquartered in Fujian, China. Since its establishment, it has always focused on the customized development and mass production of slippers, flip-flops, Crocs-style shoes and shoe accessories. The company has a complete production line, design team, R&D personnel and overseas business support team, with an annual output of more than 5 million pairs of slippers, and customers in many countries and regions such as Europe, America, Southeast Asia, the Middle East and South America.
Unlike many manufacturers who only do finished product OEM, Deran adheres to the “manufacturing + customization” dual-wheel drive strategy, continuously improves internal design capabilities and material innovation capabilities, and supports customers to create exclusive shoes from 0 to 1. This model makes Deran not only a producer, but also a design consultant and solution provider in the process of customer product realization.
In addition, Deran is also constantly exploring the application of environmentally friendly materials, such as developing and using renewable EVA materials and degradable packaging bags, and providing environmentally friendly slipper products that have passed European REACH and US CPSIA tests for multiple overseas brands.

Analysis of Deran’s OEM & ODM service advantages
OEM means that the customer provides the design and the manufacturer is responsible for production. ODM, on the other hand, means that the manufacturer provides the design together. Deran has very strong execution capabilities in both directions, especially in ODM, where it has accumulated a lot of practical experience.
R&D and design capabilities are one of Deran’s core competitiveness. The company has an independent product design center equipped with CAD drafting engineers, sample plate makers, and structural process analysts, which can quickly generate 3D models and material matching solutions based on the concept drawings, reference samples or market trend drawings provided by customers.
Rapid proofing and small-batch trial production are important advantages that distinguish Deran from large traditional factories. For e-commerce customers and customized brands, Deran has a minimum order quantity of as low as 300 pairs, and provides 7-10 working days of proofing services, which greatly shortens the customer’s cycle from idea to product launch.
Full-process visual management is a thoughtful service created by Deran to improve the cooperation experience. Each customer will be connected by a professional project manager. From confirming needs, proofing feedback, production progress to shipping arrangements, the ERP system can track progress in real time and accept remote file and drawing transmission.
In addition, Deran also provides overall solution support from product structure, shoe style, material technology to packaging design, truly helping customers build a product system with commercial competitiveness.
Detailed explanation of the slipper customization process: from design drawings to mass production and delivery
Choosing Deran for OEM/ODM slipper customization is not just about finding a foundry, but finding a co-creation partner. The following is Deran’s standardized slipper customization process:
Step 1: Demand communication and data confirmation
The customer submits a design drawing, reference sample or concept description, and the Deran project manager assists in sorting out the development direction, including target price, size specifications, market positioning, etc.
Step 2: Material selection
Recommend suitable materials based on product positioning, such as:
- EVA (lightweight and comfortable, suitable for flip-flops)
- TPR (strong elasticity, suitable for outdoor sandals)
- PU synthetic leather (fashionable thick-soled style)
- PVC or rubber (anti-slip and wear-resistant)
- And provide material samples for customer confirmation.
Step 3: Sample development and feedback
The proofing cycle is usually 7 to 10 working days. Customers can make modification suggestions, and the design team will cooperate to modify the structure, shoe shape or pattern color until they are satisfied.
Step 4: Production scheduling and quality inspection process
After the sample is confirmed, the order contract is signed and production is scheduled as needed. Production is divided into raw material procurement, mold debugging, molding, post-stage inspection and packaging. Deran implements the four-level quality inspection standards of IQC→IPQC→FQC→OQC to ensure that each batch of products is qualified before leaving the factory.
Step 5: Packaging and delivery logistics
Customers can choose customized color boxes, OPP bags, paper cards or environmentally friendly packaging, and Deran can also assist in arranging FOB ports or overseas warehouses for transportation.
