In cross-border manufacturing, a “replica order” is never a simple case of “copying blindly” — it tests the ability to disassemble unknown products, the precision in controlling process details, and more importantly, the emergency response efficiency and sense of responsibility when facing unexpected challenges. In the summer of 2024, Ehisen received an inquiry from a German client. There were no detailed drawings or clear parameters, only a simple request and a few product photos with limited information. Thus, a nearly six-month replica journey full of challenges yet ultimately gaining recognition began.

June Offensive: Phased Breakthrough of Samples Without Plastic Parts

The road to replication is never smooth, and every step forward is accompanied by unknown tests. On June 26, 2024, the replication of products without plastic parts finally achieved a phased breakthrough, basically completing the restoration of the core structure. We repeatedly calculated tooling costs, minimum order quantities of raw materials, and production costs, not only considering our own production capacity and efficiency, but also helping clients control costs and ensure cost-effectiveness. After multiple rounds of communication and negotiation, we finally agreed on the quantity of the first batch of samples with the client and successfully completed the initial supply. During the days waiting for feedback, the team was always on tenterhooks, fearing that there might be omissions in any details. Until August 20, the client’s test feedback arrived as scheduled — the recognition and affirmation in the tone dispelled all anxieties, and the first batch of orders without plastic parts was successfully confirmed. However, the joy did not last long. At the same time, the replication of products with plastic parts was quietly facing a more difficult and tedious challenge, testing our patience and professionalism.
Solving the Puzzle: Deciphering the Hidden Structural Difficulties of Plastic Parts

Initially, based on visual inspection alone, we subconsciously judged that the plastic part was just a simple annular structure that only needed to be sleeved on the metal component, without complex adaptation processes. But when we tried to manually remove the plastic part from the sample, no matter how hard we tried and dug repeatedly, even if we dug deep grooves in the plastic part, it still clung tightly to the metal component without moving. It was not until then that we suddenly realized that this seemingly ordinary plastic part had a much more complex internal structure than we had guessed, hiding a connection design we had not anticipated. Our previous underestimation made us take a small detour. Without hesitation, we immediately decided to launch destructive testing again, not missing any details. At around 8 o’clock that evening, the sky outside was already dark, but the lights in the office were still bright. The engineer in charge of disassembly returned to the office with a look of excitement, holding the disassembled components. There was no trace of fatigue from working overtime late at night in his eyes, only the joy and determination of solving the puzzle and getting closer to the client’s needs step by step — this inner sense of responsibility and perseverance in the face of difficulties is the core confidence that allows Ehisen to win the trust of clients.
August Correction: Upholding Quality Bottom Line Amidst an Oolong Incident

After the successful disassembly of the plastic part, a new round of drawing and adaptation work began in full swing. For replication, the precise coordination between part tolerances and production tolerances is tantamount to a “life-or-death line”. The slightest deviation may cause the final product to fail to function normally. Especially for plastic parts we are not familiar with, the requirement for precision is extremely strict. To ensure that the replicated product not only has the exact same size as the sample but also perfectly matches the material, thereby guaranteeing the client’s performance requirements, we did not rely solely on experience to judge. Instead, we took the initiative to cooperate with authoritative third-party testing institutions to conduct comprehensive and precise testing on the material composition of the plastic part, confirming each material parameter one by one to ensure that every data is true and reliable, laying a solid foundation for subsequent production and replication.
Unexpected Oolong: Dispute Over Accessories Halts Replication

Just as everything was progressing as planned, a sudden oolong incident disrupted the originally smooth workflow: the worker responsible for cutting the sample did not notice whether internal accessories were missing while focusing on the cutting process; while the engineer who participated in the pre-cutting inspection firmly stated that besides the spring, there was another small accessory inside the sample before cutting. Both sides insisted on their own opinions with evidence, leading to a stalemate and a temporary halt in replication work.
Frank Response: Resolving Disputes with Responsibility

For a time, there were different voices within the team. Some suggested that we should first draw samples based on the existing drawings for the client’s preliminary testing, avoiding excessive entanglement in a small accessory and delaying the overall progress. However, after a quick seminar by the company’s core team, we finally reached a consensus: replica orders allow no perfunctoriness or compromise. Even if it takes a little time, we must ensure the completeness and accuracy of every detail. This is not only responsible to the client but also to Ehisen’s own brand. Subsequently, the responsible salesperson took the initiative to contact the German client, frankly explained the current dispute, and politely proposed that if the client understood the internal structure of the sample, they could provide relevant guidance; if the client was also unsure, they could send another sample to facilitate our accurate verification.
Improving Mechanisms: Reviewing and Optimizing to Prevent Future Problems

Thanks to the good cooperative foundation established earlier and our honest and pragmatic attitude, the client readily accepted our proposal without any complaints. After receiving the sample again, we immediately established a two-person verification mechanism. Every measurement and inspection is jointly responsible for and cross-checked by more than two people, and the entire testing process is photographed and archived to ensure that all details are traceable and verifiable. Finally, we accurately mastered the specifications, appearance, and installation position of the last part, successfully replicated all parts of the product, and smoothly got out of this small storm. It also made us more determined to adhere to the original intention of “working rigorously and treating clients with integrity”.
Chapter 4: Iteration in Autumn and Winter 2024: Optimization and Implementation, Precipitating Standardized Processes with Experience
Autumn and Winter Offensive: Manual Trial of Plastic Part Assembly

After the replication of parts was completed, the assembly of plastic parts became a new challenge. Since mass production had not yet started, to avoid damage to parts during mechanical assembly, the workshop masters had to manually assemble them with rubber hammers in the assembly workshop, testing the fit degree after each tap. Repeating the same action for a long time, the masters’ hands were pressed with indentations by the parts, but they never complained — this persistence in pursuing excellence is the confidence that Ehisen guarantees product quality.
Optimization Breakthrough: Solving Adaptation Problems After Long-Distance Transportation

But a new problem arose: the samples that were tightly assembled on our side could be easily rotated after arriving at the German client’s hands via long-distance transportation — it turned out that the thermal expansion and contraction characteristics of the plastic parts affected the tight fit effect. Our engineers immediately re-examined the tight fit plan, abandoning perfunctory temporary adjustments, and instead starting from core aspects such as part size and structural adaptation, repeatedly testing and adjusting parameters. Finally, the product was optimized into a structure that “cannot be easily pulled out after installation”, fully meeting the client’s requirements for tight fit.
Detail Upgrade: Meeting the Client’s Actual Usage Needs

In addition, we accurately adjusted the different colors of plastic parts according to the client’s needs, making it easier for the client to distinguish products of different specifications. We demonstrated professionalism through detailed services, further narrowing the distance with the client and letting the client see our sincerity in proactively thinking for them.
Experience Precipitation: Implementation of Standardized System for Replica Orders
From the hot summer to the cool early winter, the nearly five-month sample restoration test finally came to an end. The client highly recognized the mass purchase test results of products with plastic parts. This nearly six-month replication journey not only allowed us to win the client’s trust but also enabled us to precipitate a complete set of standardized operating processes for replica orders, transforming every experience and lesson into confidence in serving clients in the future.

System Construction: Full Coverage of Four Major Standardized Modules
Combining the experience of this order, we have established four major standardized systems: first, standardized inquiry response. For unspecified inquiries without drawings or parameters, a fixed process of “proactive guidance + sample sending and actual testing” is formed to avoid information deviations; second, standardized testing and replication. Clarify the applicable scenarios of destructive testing, infrared testing, and third-party material testing, and establish a measurement mechanism of two-person verification and photo archiving to ensure replication accuracy; third, standardized problem-solving. Sort out reusable process optimization schemes for common problems such as welding, deformation, and assembly to improve the processing efficiency of subsequent orders; fourth, standardized delivery guarantee. According to the client’s packaging requirements, add special packaging equipment; customize industrial assembly devices in combination with the final assembly process to ensure the consistency of mass production; when delivering in batches, equip installation tools and spare parts according to the order ratio to ensure the client’s smooth installation.
Chapter 5: Looking Back from 2024 to 2025: Adhering to the Original Intention, Being the Most Reliable Partner for Clients
Looking back at the starting point of this replication journey, what best reflects Ehisen’s professional background is the serious attitude and efficient processing ability when facing the German client’s unspecified inquiry — different from the impetuous practice of some enterprises in the industry of “blind quotation and perfunctory response”, when receiving an inquiry with only one sentence of demand and a few photos with limited information, we did not slack off at all, let alone give up easily. Instead, with an extremely serious attitude, we proactively sorted out the core pain points of the inquiry and efficiently promoted each step of the connection.
We deeply understand that every detail of a cross-border inquiry is crucial to the success or failure of subsequent cooperation; unspecified needs are never an “excuse to refuse”, but an “opportunity to show capabilities”. Faced with the client’s inability to provide detailed parameters, we did not rush for success, but quickly launched the inquiry response plan: sorted out the core information required for quotation and replication at the first time, sent similar successful titanium anode manufacturing cases synchronously to guide the client in supplementing key details; after unsuccessful communication, we efficiently proposed the sample sending and actual testing plan, clearly informing the client of the necessity of sending samples and the subsequent testing process, which not only reflects our professional rigor but also shows our sincerity in solving problems for the client.
From receiving the inquiry to proposing the sample sending suggestion, from sorting out information to contacting the client, we broke the information barrier with efficient response speed and serious connection attitude, and also let the German client see Ehisen’s reliability and professionalism — this attitude of not being perfunctory, not being impatient, proactively thinking for the client, and efficiently solving problems not only laid a solid foundation for subsequent replication cooperation but also became the core competitiveness of Ehisen in deepening cross-border manufacturing and winning client recognition. It is precisely this attitude that allows us to stand out among many peers and gain the client’s trust and favor.

Today, whenever we review this German order, we deeply realize that the attitude towards inquiry response is the business card of an enterprise. Those proactively sorted out information, efficiently proposed schemes, and patient and careful connections, although seemingly insignificant, contain Ehisen’s sense of responsibility and professionalism — we never flaunt ourselves with gorgeous words, but prove with every serious response and every efficient action that we have the ability to undertake every challenge and the confidence to be the most reliable partner for clients. This is also the original intention of us subsequently incorporating inquiry response into the standardized system and continuously optimizing service efficiency.
We deeply understand that cooperation in cross-border manufacturing relies not on gimmicks, but on professionalism, responsibility, and reliability. In this somewhat impetuous industry, Ehisen always maintains a “slow passion” — not rushing for success, not perfunctory, taking every order seriously, solving every problem with care, putting the client’s needs first, and engraving product quality in the heart.
This replica order for the German client is not only a test of technology and capabilities but also a precipitation of experience and systems. In the future, Ehisen will continue to carry this seriousness and responsibility, continuously optimize and implement the standardized process of replica orders, and with professional services and reliable products, become the most assured and trustworthy choice in every client’s supplier list.
Today, whenever our products arrive at the German client’s hands across mountains and seas, the messages exchanged no longer have the initial temptation, but more mutual understanding and recognition. Those lights of late-night seminars, the palms with indentations in the workshop, the persistence in repeated testing, those moments of not compromising for a detail and not being perfunctory for a trust — these are not only the testimony of Ehisen’s strength but also the temperature hidden behind our professionalism. We never claim to be the best in the industry, but we always take “client reassurance and our own peace of mind” as the bottom line, solve problems with excellent technology, treat cooperation with a sincere attitude, and ensure quality with a standardized system. Strength gives us the confidence to undertake every challenge, and temperature allows us to retain every trust. This is the confidence that Ehisen moves forward steadily in cross-border manufacturing, and also the original intention we will adhere to in every step of the future.
