Service

The warranty period is 12 months from the date of installation at your facility. During this period, all mechanical failures and damaged parts are repaired or replaced free of charge, including labor and parts costs. After the warranty period, Yucheng supplies all spare parts at cost price with no markup. Whole-life service is guaranteed for every machine model.

Yes — comprehensive after-sales support is a core part of every Yucheng machine purchase. This includes:

● 24/7 phone, email, and video call technical support

● On-site installation and commissioning by Yucheng engineers

● Operator training at your facility

● Lifetime spare parts supply at cost price

● Production recipe and formula assistance

All of these services are included during the warranty period. Most are available on an ongoing basis after warranty expiry.

Our engineers are reachable 24 hours a day via phone, email, WhatsApp, and WeChat. For most issues, a video call is the fastest resolution path — your operator films the machine in operation, our engineer observes and diagnoses the issue in real time, then walks your team through the adjustment. Most production issues are resolved remotely within 30–60 minutes without requiring any machine downtime beyond the diagnostic call itself.

Yes. Yucheng dispatches engineers to your facility for installation, mechanical setup, electrical connection, parameter configuration, and a full commissioning trial run with your actual dough and filling. We will not leave until the machine is producing at specification and your team is trained to operate it. Installation service is free during the warranty period — including engineer travel and accommodation costs covered by Yucheng.

Contact our 24/7 support line immediately. Our engineer will assess the issue via video call first. If the problem cannot be resolved remotely, we will dispatch a technician to your location. During the warranty period, all repair costs — labor and parts — are covered by Yucheng. After warranty, parts are supplied at cost price and labor costs are discussed case by case depending on issue type and location.

Yes. Yucheng encrusting machines are designed with advanced feeding and cooling systems to handle a wide range of dough types and fillings. Supported dough types include wheat flour dough, glutinous rice dough, shortcrust pastry, semolina, and more. Filling compatibility includes bean paste, lotus paste, custard cream, meat, seafood, cheese, chocolate, fruit jam, date paste, and solid ingredients such as salted egg yolk and nuts. Our food technologist team provides recipe guidance to ensure compatibility with your specific ingredients.

Yes — and this is genuinely part of the service, not an upsell. Yucheng provides baseline recipes for all major product types we support and helps adapt them to your local flour, filling ingredients, climate, and taste preferences. We have formula adjustment experience across 60+ countries and 40+ product types. Recipe support is free of charge with every machine purchase and remains available for the life of the machine.

Yes. Yucheng offers full customization for both individual machines and complete production lines. We can customize mold shapes and sizes for unique product forms, configure multi-filling setups, adapt machines for specific voltage/frequency requirements, and design entire line layouts around your factory floor plan. Turnkey production line solutions are available — contact us to discuss your specific requirements.

Contact our service team with your machine model number and the part required. We maintain stock of all wear parts, molds, screws, cutting wires, and electronic components for every machine model we have ever produced. Parts are supplied at cost price after warranty expiry. Shipping timelines depend on destination — air freight is available for urgent requirements. Most standard parts ship within 2–5 business days.

Capacity varies by model and product type. Our encrusting machines range from 10 to 120 pieces per minute for standard filled products (15–120g per piece). Full automatic production lines can achieve 10–1,000 pieces per minute depending on configuration. The right model depends on your target output, product weight range, and filling type — contact us with your specifications for a tailored recommendation.
