Malden Surgical Company (Pvt.) Ltd. is a well-known company in thefield of medical industry. The quality and reliability of itsinstruments has got a good reputation over a period of 25 years. Weproduce all kinds of surgical, manicure, pedicure and dentalinstruments. We are specialist in all types of scissorsmanufacturing. The main steps that our instruments undergo whilemanufacturing are described here-under briefly:1. MATERIAL USED: Always a best quality stainless steel material ispurchased from steel manufacturers. Two kinds of series i.e. 300,410 and 420 of stainless steel is used for production of DentalInstruments.2. MATERIAL TESTING: The purchased raw material is thoroughlytested under PQA. Authority. A rigid quality control policy isbeing adopted before releasing to production. This test is taken tocheck the standard of steel as per desired specifications and isconsidered the most important factor of our business.3. FORGING & HAMMERING: After testing, the stainless steelstrips/bars are divided into different sizes as per ourrequirements and our highly experienced craftsmen are specializedin forging (Hot/Cold Drop) to perform all standard press operationsin forming and deep drawing of all type of instruments. We annealthe forging and prepare for the milling process.4. MACHINE & TOOL WORK: Our highly skilled technicians have agreat knowledge about machine milling process. We form accuratelymale/female portion of box-joint forceps, as well as, serrations/retches in uniformity. We are equipped to mill, drill, bore turnand grind all type of metals. We have in house facility of customtool and die production, maintenance and repair.5. FILLING: We are specialized in hand–made fabrication. First, weassemble male/female portion after setting/adjusting of ExtractingForceps and Scissors, tips, serrations, ratches in uniformity andfile precisely to make it semi-finish under strictly qualitycontrol specifications. We are now moving from basic handmanufacturing techniques to mechanization to production run.6. HEAT TREATMENT: All instruments are being tempered maintaining“Rock-Well Hardness” for Extracting Forceps & Retractor 45º to50º degree and Scalar, Gauges and Scalpel 50° to 55º degree. A testis taken to check the hardness after tempering of each lot tomaintain the uniformity and, before proceeding further, we cleanall instruments by various chemicals. In addition, we will buyspecialized Q/C equipment in near future to meet special customerQ/C. specifications.7. RIVETING & WELDING: We perform a wide variety of assemblyoperations from prototype quantities to production run. We rivetprecisely each instrument such as, Extracting Forceps &Retractor, etc. But, for some kind of instruments, we use spotwelding.8. GRINDING & POLISHING: For precise grinding and excellentfinish, we specialize in applying polishing wheels to belts toimprove the overall finish in high uniformity utilizing best ofpolishing luster. We use electro-plating plants to polishserrations/ratches and joints of stainless steel instruments. Forsatin/matt finish instruments, we use glass heads to achieveuniformity. All instruments are being polished under rigid qualitycontrol specifications.9. PASSIVATION: This method actually provides the instruments withits corrosion resistance properties. Passivation, which follows thefinal polishing step, is a chemical bath, which creates an oxidizedlayer on the surface of instruments. We are now equipped with mostmodern process.10. ULTRASONIC CLEANING: We are full equipped with most modernultrasonic cleaning plants imported from “Branson CleaningEquipment Co. USA”, and all instruments are being cleaned properlyutilizing various chemicals such as, Tri-Chloroethlyine etc.11. INSPECTION & STAMPING: We inspect all instruments underrigid Q/C. specifications and give the assurance to our relativeclients that all instruments shall be free from all defects suchas, burrs, sharp edges, cracks, pitting, scratches, grease /excessive oil and foreign matters etc. We also guarantee for itsworkmanship. For stamping, we use both process i.e. die sunk andelectrolytic marking and are being marked under customer’sspecifications.12. PACKING & LABELING: We pack all instruments under strictlyQ/C. specifications as per customer’s demand. Normally, we packindividually in poly bag and further 12 pieces in one boxmentioning outside with Part Number, Description and Lot Number.All instruments are packed in polybags with adequate desiccant ineach poly bag to absorb moisture. Mostly, we are packaging andlabeling as per customer demand.
