Technical Manager & Rubber Technologist
I am responsible for all the technical aspects of rubber and moulds. I develop new moulds with the design engineer and maintain contact with compound suppliers about existing and yet to be developed rubber mixtures. We are dynamic and flexible as well as highly inventive and innovative. Good advice about product design is important but the choice of a compound with the right mechanical and chemical properties for a dedicated application is definitely just as essential. The diversity of our product range and our expertise in rubber products makes us special In terms of dimensioning and weight, but also of function. One product will be loaded dynamically while another is loaded statically; almost without pressure or with a pressure that may run into millions of kilos. RIS Rubber stands for boundless production possibilities.
Marjelle Hoekman | RIS RUBBER

As a Sales staff member, I like to think I pull my weight within this interesting and dynamic business, where I work with great pleasure each and every day. My duties are very diverse; they include contact with customers and the entering and processing of orders, so I am involved right from the start up to and including the delivery of an outstanding product. Good communication and cooperation with customers and colleagues are key to me as I go about my work.
Marije Leijenaar | RIS RUBBER

Marketing and communication are my responsibility at RIS Rubber. I joined RIS in 2019, and once the diversity of the customer-specific rubber products had sparked my interest, the setting-up of this marketing department came naturally to me. My duties include the writing of newsletters and provision of information on the internet, as well as maintaining our social media channels and ensuring that all marketing-related business is running smoothly. RIS often has a presence at industrial fairs, and it is also my responsibility to organise and support such promotional events.

Quality Control
My name is Jan Kroonenburg and I work as a quality controller at RIS Rubber. Among other things, my work includes performing first product checks, intermittent checks, entry checks on metal parts and final checks, as well as measurement reporting. I also sample the products from new and adjusted moulds to check that they conform to the measurements specified by our customers. The performance of trial mouldings (compression set measurements) is another of my tasks. My other duties include calibrating measuring equipment and producing work instructions for my colleagues to ensure the smooth running of the production process.

QESH Manager
To my mind, what is really special about RIS Rubber is the technology that is hidden behind seemingly simple products. After all, we jointly develop and produce innovative, high-quality industrial moulded rubber products whereby we also take seriously our footprint on the environment and people. It is my duty to realise those objectives in terms of quality, health, safety and the environment, and to secure them throughout our development and production process. Being the QESH (Quality, Environment, Safety & Health) Manager, I am co-responsible for the company’s quality and HSE strategy and its implementation. Its main objective is to supply a 100% quality product to our customers. And obviously we want our stakeholders to be aware of our accountability for operating safely and responsibly.
Stefan Reddeman | RIS RUBBER

As a member of the active and innovative RIS Rubber team, I attend to all manner of customer business, which means that as well as visiting clients, I also maintain contact by mail or telephone. All members of our Sales department have their own tasks, but we all cooperate within a very well-structured system. One of my tasks is the handling of quotes. I feel that it is especially important at the time of the initial enquiry that we understand fully what the customer wants. After all, the better we can interpret the customer's question, the more successful our solution will be. Because the enquiries are so diverse this is always a challenge, but crucial for giving shape to the customer's idea.
Wouter Rietdijk | RIS RUBBER

Managing Director
RIS Rubber is, and has always been a marvellous business, and the team of great people working for us deserve most of the credit. Day in, day out, our people work with the sort of passion you might expect from them if it were their own business. I therefore consider it a true privilege to be able to head RIS Rubber. To my mind, one of the most intriguing aspects of our business is the first product stemming from a new mould. Not only does it reflect the end of a conceptual pathway that usually begins with an idea, a drawing or a sketch, it also marks the beginning of a product's life cycle, and often of a longstanding collaboration with a customer.

Finance, Purchase & HRM Manager
Long-term vision is undoubtedly the strength of RIS Rubber. We have built up a network of quality suppliers, with whom we have solid price agreements both at home and abroad. This means we can offer competitive prices to our clients ourselves. At the same time, thanks to our transparent provision of financial information and the outstanding delivery reliability of our suppliers, we can meet the delivery times agreed. That’s why RIS Rubber is known as a reliable and flexible partner for high-quality moulded rubber products. What appeals to me is that every product – whether large or small – is underpinned by the extensive technology delivered by a technical team of 160 people, whereby all employees contribute to achieving the high quality of all our products.
Jitze Stegenga | RIS RUBBER

R&D Engineer
I have been working with RIS Rubber since 2005, when I finished my study in Technical Economics. My work involves the conversion of a customer’s idea into a functioning product. To do this, I need to make use of the proper resources. I might, for example, have to calculate the properties of rubber models by means of an FEM software package. In the follow-up stage, I assess the actual products by carrying out practice trials. This means I can match theory with practice at a fast pace. The scope of my work involves the whole of the process, ranging from the drawing board to final delivery to the customer. The wide range of product groups makes my job one big challenge. And this versatility is definitely characteristic of RIS Rubber.
Joost van Uden | RIS RUBBER

Sales Director
RIS has a lot of knowledge and possibilities in the rubber field. From my role, I continuously try to bring supply and demand together in order to create a beautiful cooperation. The development, production and testing of rubber products is our expertise. This, in combination with the special properties of rubber, give us the opportunity to be active in many industries. The great diversity and the wide network make this work very enjoyable and challenging.
Maico Zuidweg | RIS RUBBER

Mould Engineer
I feel that the technical features incorporated in our products are a highly intriguing aspect of RIS Rubber. I had no knowledge whatsoever of rubber products before I joined the company; I simply thought that rubber was just rubber. But producing moulded rubber products entails much more than just the material. To my mind, the interesting part of my work is the devising and development of the moulds and parts from which a concrete end product ensues. I have been working with RIS Rubber as a trainee Mould Engineer since January 2019, and already I am entrusted with the drawing and repair of moulds.
