What information do you need to prepare a quotation?

Compliance is handled project by project, based on your target market and product category. We can support material declarations, supplier compliance documentation, and relevant test reports for requirements such as REACH, RoHS, and packaging-material regulations. Our certified management systems, including ISO 13485 for medical devices and IATF 16949 for automotive, are maintained and audited regularly. Certification details are managed according to the applicable site, scope, and validity period. We also hold BSCI social compliance certification and Costco Wholesale Code certification, supporting entry into international retail supply chains.

For intellectual property, we routinely sign nondisclosure agreements and strictly control access to customer drawings, samples, designs, and commercial information. Engineering data is stored and shared on a need-to-know basis, and internal training reinforces confidentiality awareness across every department. Many of our customers launch innovative products with us, and protecting your designs is a precondition for that long-term trust.

Yes. Packaging is the last line of defense for product quality, and we treat it as an engineering discipline rather than an afterthought. Depending on the product and your requirements, we can support packaging reviews, full-carton drop testing, simulated transportation testing, and packaging improvement with re-verification after changes. These activities reveal potential damage, movement, abrasion, or cosmetic defects before products leave the factory.

Our packaging validation takes place in a dedicated packaging validation and warehouse area, with results documented for shipment traceability. We also monitor evolving regulations. For example, the EU Packaging and Packaging Waste Regulation (PPWR), which covers recyclability, PCR content, and EPR obligations, and can advise how such requirements affect your packaging choices for European markets. Test standards are agreed at the beginning of the project, so everyone knows what "safe arrival" means before the first carton ships.

Yes. Starting from molded parts, surface-finished components, and purchased parts, we provide subassembly, final product assembly, functional testing, cosmetic inspection, and packaging on six finished-product assembly lines. Typical examples include micro-motor and blower integration, heating element core assemblies for high-speed hair dryers, micro dispensing pump modules for smart soap dispensers, and complete finished products such as air purifiers and smart pet feeders.

Before mass production, we agree with you on test items, inspection standards, fixtures, work instructions, and traceability requirements. Our assembly teams support NPI (new product introduction), component purchasing integration, and batch traceability, so you get one accountable partner from parts to packaged product. This is how many customers simplify their supply chain: instead of coordinating molders, coaters, printers, and assemblers separately, they manage a single program with one point of contact. This reduces communication costs and shortens issue-resolution time.

Quality at Simblong is built into every stage, guided by our certified management systems: ISO 9001, ISO 14001, ISO 13485 for medical devices, and IATF 16949 for automotive. In practice, this means IQC incoming inspection, first-article inspection (FAI), in-process IPQC, statistical process control (SPC), critical-dimension measurement with CMM and vision measurement systems, cosmetic inspection, functional testing, and batch traceability. Together these form a closed-loop quality system from raw material to finished product.

When a nonconformance occurs, we contain the affected products immediately, identify the root cause, implement corrective action, and verify effectiveness before shipments resume. Our 800 m² Class 100,000 cleanroom further protects sensitive optical, electronic, and medical parts from particulate contamination, while packaging drop and transport simulation tests ensure that quality survives the journey to your customers, not just the production line.

Our in-house surface-finishing capabilities include spray painting on two automated coating lines, UV coating, soft-touch and skin-feel coatings, vacuum metallization (PVD), silk screen printing, pad printing, laser engraving, and other decorative marking processes, supported by 10+ printing and marking machines. Typical applications include gradient-sprayed power bank shells with vacuum plating, high-gloss painted housings, printed keyboard enclosures and keycaps, and decorated beauty and personal care devices.

Appearance quality is engineered, not left to chance. Before production, we confirm color, gloss, adhesion, abrasion resistance, and cosmetic acceptance standards with you, using color samples and approved appearance masters. During mass production, coating performance is verified through standardized testing, including adhesion and alcohol-rub testing. And inspection against the agreed cosmetic standards keeps every batch consistent with the approved sample.

We process a wide range of thermoplastics and engineering plastics, including ABS, PC, PC/ABS, PP, PA6/PA66, POM, PMMA, TPE, TPU, AS, glass-filled materials, and high-temperature engineering plastics. For demanding applications we also work with modified materials. For example, flame-retardant PC/ABS for robot vacuum housings and chassis, and optical-grade materials molded in our Class 100,000 cleanroom for sensitive optical and electronic parts.

Material selection is never just a datasheet decision. Our engineers recommend materials based on mechanical strength, heat resistance, flame-retardant requirements, chemical resistance, surface appearance, cost targets, and regulatory requirements. And we validate the choice through mold trials and pilot production before mass production. For two-shot and overmolding projects, we also verify hard/soft material compatibility and adhesion, so the combination performs reliably throughout the product's lifetime.
