Customer Story: 20+ Years Together—Why Tianyue Keeps Choosing Welltec

For established manufacturers, choosing new equipment is about more than comparing specifications.

As products evolve and production expands, manufacturers must ensure new equipment fits existing molds, processes, and future production needs.

Over the past 20 years, Tianyue has continuously evolved-from expanding product lines and production capacity to upgrading its manufacturing system. Welltec has grown alongside Tianyue throughout this journey. More important than any single machine specification is why both companies continue to choose each other as production needs evolve.

01.From Injection Molding to Full-Service Manufacturing

Founded in 2002, Tianyue Plastics initially focused on injection molding. Over the past two decades, the company has expanded its capabilities to include mold development, injection molding, surface treatment, and assembly, serving industries such as home appliances, automotive, and small appliances with integrated manufacturing solutions.

As its manufacturing capacities continue to expand, Tianyue has also upgraded its production system, gradually moving toward digitalization and lean manufacturing.

Moving from standalone injection molding to a more integrated manufacturing chain has placed higher demands on production management and molding capabilities. Dimensional variations can affect downstream assembly, unstable surface quality can increase quality control pressure, and fluctuations in production rhythm can further impact scheduling and delivery.

As product variety and manufacturing processes expand, Tianyue’s equipment requirements have shifted from simply “making the product” to ensuring dimensional accuracy, appearance consistency, mold compatibility, and long-term process stability.

02.Every Expansion, A New Choice

Over the past two decades, Tianyue’s equipment investment has evolved step by step. As product lines expanded, capacity increased, and molds and processes changed, different models and tonnages of Welltec machines were introduced to meet different production needs. Each application requires different capabilities. Small parts demand high injection repeatability to maintain consistent dimensions and appearance, while larger products require careful consideration of clamping force, platen strength, mold compatibility, and process stability.

This means every expansion was not simply a repeat of the previous investment. Each decision was made based on the specific products, materials, molds, and production requirements at that stage.

The key to the partnership lasting over two decades lies here: as Tinayue’s products and capacities continued to evolve, Welltec was able to provide the right equipment solutions for each new production challenge.

03. Long-Term Partnership, Proven Through Production

Past experience alone does not guarantee the next purchase decision. For manufacturers continuously expanding capacity and taking on new production tasks, every new equipment investment requires a fresh evaluation of whether the machine can meet future product and delivery requirements.

According to Tianyue’s production team, once the process conditions are stabilized, Welltec machines maintain consistent production performance, reduce repeated adjustments, and make product consistency easier to control.

This value may not be fully evident on the first day of operation, but it is repeatedly proven through long-term production, product changes, and delivery challenges.

For mature manufacturers, reducing procurement risk depends not only on brand recognition, but also on whether past production experience can continue to meet today’s requirements.

04. From Equipment Partnership to Production Collaboration

In 2021, Tianyue’s smart manufacturing workshop was put into operation.With centralized material feeding, automated part removal, and digital management introduced into production, injection molding machines became an integrated part of the entire manufacturing chain rather than standalone equipment.

Tianyue’s smart manufacturing system was developed based on its own production needs. Welltec focuses on the injection molding process, ensuring stable operation and process compatibility while working seamlessly with material feeding, part removal, and production cycles.

From early injection molding operations to a multi-process manufacturing system; from single machines to multi-tonnage solutions for different production needs;from traditional workshop to increasingly automated and digitalized operations-Tianyue has continued to evolve, and so have its equipment choices.

Over two decades, what has truly been proven is not just the length of the partnership, but Welltec’s ability to support new production challenges as customers move into the next stage of growth.
